1 February 2015 - Lowburn Harbour, Lake Dunstan, Cromwell, Otago

It rained heavily through the night, but only puddles gave credence to the nocturnal weather. The day dawned bright and with promise.

We hung about our spot on the canal, having agreed with Pam that we would meet up and exchange contact details. We’d met up with her on the opposite bank of the canal last night, sitting on a stool doing Sudoku puzzles while fishing, the combination of cerebral and sports exercise. Her husband was downstream fishing and pondering the matters of the world as is the case with most leisure fishermen and did not notice us at all. We discussed motorhomes, children, travel and retirement with Pam, who harked from Christchurch, but had been on the road for about as long as us. We hit it off and could have stood in the evening air chatting and swapping life stories for several hours but I knew that Chris was keen to return to the camper to see how the cricket was coming along. So we agreed that she would pop along in the morning since we were in no hurry to leave. And so we hung about until after ten, and then popped along to their motorhome ourselves thinking it rude to simply head away with no word, but their blinds were still drawn, so we left without following through. A  shame really because I liked her immensely and I am sure her Graeme would have been as likeable; she was too forthright a person to have suffered anyone less so.

The road south took us to Omarama, centre of the gliding universe if you are to believe all the hype; the area’s northwest thermals being particularly suitable for high altitude long flights, something we ourselves never experienced when we dabbled briefly in the sport in Northland many years ago. Apart from that fame, Omarama lies at the crossroads of the highway coming up from Oamaru on the east coast and that running more or less north-south that we were travelling. 

We had called and lingered here before, staying at the DOC camp of the Ahuriri River, another lovely braided river which at the right time was host to a million Russell Lupins blooms. From here one can drive the short gravel road to the Clay Cliffs, a bizarre moonscape resulting from two million years of erosion of layers of silt and gravel exposed along the active Osler fault line. The cliffs are on private land and the owner asks for a token donation at the gate to “maintain the road”. Six or seven years ago it was obvious that the donations were funding his holidays rather than any upkeep of the road; it really was in an appalling state. Having said that, if it is the first time one has come this way, the Clay Cliffs are certainly worth a visit.

But instead we found our way into the local Four Square store and came out bearing a large Boston Bun which should, by volume, last us several days; time will tell. We consumed one quarter with our morning coffee; I suspect the next portions should be larger or it will grow stale!

From here we continued up the Ahuriri River, across flats strewn with small rocks, yet harrowed for planting; we wondered at the state of the machinery subjected to such materials. On the riverside of the road we saw small cairns of stones, as we had on our last trip through. One wonders at the builders; perhaps travelling children pausing for a break, filling the minutes of their boredom, before the advent of iPads and such?

The road passes up over the Lindis Pass, through dry steep barren mountainous country, an elevation of 971 metres. We stopped at the lookout to take a photo or three, and to check out the memorial. This is one dedicated to not a Lord as that at Lake Pukaki, but to an Earl who gifted another scourge on conservation; the red deer.

In March 1871 the 11th Earl of Dalhousie of Brechin in Scotland shipped seven deer to Dunedin which were liberated in the Lindis Pass area after being shipped further to Oamaru, then transported over the pass by bullock wagon. It is they who form the base of all the feral red deer who have added to the decimation of the high country natural vegetation. God bless the Earl!

The road south of the Pass is far steeper, more windy and slower, more than we recalled. But then when I checked the elevations later, we should not have been surprised. Omarama sits at an elevation of 420 metres ASL, the Lindis Pass at 971 metres ASL and Tarras to the south where the land levels out into the upper reaches of the Clutha River valley, sits at 268 metres ASL. Say no more!

Tarras is an interesting spot, little more than a school and a collection of shops that base their existence on the fame of Shrek, the hermit merino sheep. Ah, the wonders of Shrek! This very woolly and long neglected unshorn ram gained international fame in 2004. The story of how the shepherd caught the sheep with the mammoth fleece that had avoided being shorn for six years captured national, even international, attention. Media from around the world reported on Shrek being shorn of his 22 kg fleece. Alas, under the weight and glory of his coat, he was a scrawny nondescript. But he became the subject of three books, and featured prominently in a fourth, and so we, New Zealand residents in the main, equate the name of Tarras, with Shrek. In June 2011, a the apparent age of sixteen, a very grand old age for a sheep, he died and was mourned by the New Zealand public who had bothered to note his existence in the first place. 

In 2007, or whenever it was we passed through Tarras, we did stop and visit the one shop to check out the souvenirs and left with none, far too tight with our hard saved dollars. Today, had we bothered, we could have been more discerning, checking out several in the little village that has grown out of this amazingly quaint history. 

Beyond Tarras, the road splits, right and west toward Wanaka and left and east toward Cromwell. It was this second we took, having decided our route this morning. From here one travels down river of the mighty Clutha which flows from Lake Wanaka all the way to the sea, a distance of  338 kilometres, the second longest river in New Zealand, and the longest in the South Island and the river of greatest volume in the entire country. And it is near here that the river begins its useful life as a generator of electricity, as so many South Island rivers do.

Near Bendigo, along Lake Dunstan, we pulled off and lunched. Again as so oft before, I was enthralled by the fact that a great body of water can be surrounded by such desolate dry country. This struck me in Australian when we followed the Darling River and the Murray where irrigation was not prevalent; it seems to defy the nature of the universe, that so much water can exist adjacent to much parched land.

Cromwell is New Zealand’s town furthest from the sea, and has an annual rainfall of 400 mm, a temperature range of -10 degrees Celsius to 37 degrees, on average it snows three and a half days per year and frost arrives on 174 days per year on average. Interestingly today, I February, patches of snow are clearly visible on the Pisa Range immediately to the south of the lake.

The land hereabouts is considered semi-desert with tussock, scab-weed, thyme and briar, a most uninviting group of plants. Wild flowers bloom in spring and early summer, hence their absence now.
The Clutha valley is a basin lying between two elongated schist mountain ranges, raised and tilted during the last five million years. Prominent are the series of terraces formed by the rivers transporting gravel from the glaciers; large landslides mantle much of the steeper slopes. The area is rich in mineral deposits; so typical of such inhospitable land.

Cromwell is part of New Zealand’s gold mining history, the reason that so many countries or areas of the world began their European settlement. But that history also incorporates a more modern twist and so this is an evolved (European) town.

Overlooking what was once the meeting of the waters of the Clutha and Kawarau Rivers, The Junction, later renamed Cromwell, was sited here following the Hartley and Reilly gold strikes in 1862. Early Maori hunters and traders, and European explorers, surveyor and sheep-man had left its mark. It was gold-mining which transformed the landscapes and it was the demands of the miners for goods and services which gave birth to the town. When the rush ended, farming and the coming of the railway ensured Cromwell’s survival.

Now largely under the lake, the main street of the old town once extended from the bridge which spanned the river below the convergence of the two rivers. Although the building of the Clyde Dam and the erection of Lake Dunstan have meant drowned orchards and farmlands in the Cromwell Gorge and much of the upper Clutha Valley, they have also opened the region to a new wave of settlors and the growth of tourism.

The old stone buildings still in use, the re-creation of part of the old town in the Old Cromwell Historic Precinct, and the re-creation of a Chinese mining community at the Mining Centre in the Kawarau Gorge are testament to the spirit of the community.

Robert Muldoon, Prime Minister from 1975 through to 1984, the Master of Think Big Projects, promised that “The Clyde Dam will be the best things since sliced bread!”

In 1976 the New Zealand Government approved the building of a Hydro Dam at Clyde on the Clutha River. By 1992, the Clutha and Kawarau Rivers upstream from the Clyde were flooded to form Lake Dunstan, providing water for the dam. The original town of Cromwell at the junction of the two rivers was flooded.

An estimated 280 people lost their homes, some of whom had been in the same family for generations, and although compensation was made, many never got over the loss. Six farms and seventeen orchards were submerged or made uneconomic. A further twenty five to thirty farms were affected. The creation of Lake Dunstan flooded a total of 1,405 productive acres. 

While there is no question that the dam has been able to provide much needed electricity for the country, there have been concerns expressed about the safety and on-going stability of the structure.
With the fault line running along the Clutha River bed, a “slip-joint” was incorporated into the dam’s design to withstand any credible displacement which may occur during an earthquake. Geological evidence dating back several hundred thousand years shows some of the hillsides around Lake Dunstan are prone to slippage. With over 14 kilometres of tunnels, sixty kilometres of surface drilling and seventy eight kilometres of drainage holes, the slide areas have been stabilised.

The survey pillars located through the Cromwell Gorge are markers for measuring slip movement, Although unlikely, a slip of land into the lake could cause a wave to flow over the top of the dam and flood the land beneath. A “backwash” wave could cause some flooding in the gorge toward Cromwell.

For myself, with these facts and those gleaned from the information centre when we were in Clyde some years ago, I would baulk at settling in Clyde or even Alexandra! And that was before the Christchurch earthquake.

The area of the resulting lake is 26 square kilometres, the surface at about 194 metres ASL, with a maximum depth of 60 metres. Like all such developments, there are always positives and negatives and today watching locals out water ski-ing and enjoying this manmade watery mass, it was hard to find anything negative to say.

The buildings in the old town were demolished and the land where they stood contoured to form Lake Dunstan’s shore line and lake bed. In 1985 a group of concerned Cromwell’s residents got together to save eight of the most important historical buildings from the old town. These buildings are now part of the Old Cromwell Town Historical precinct where we first headed on arrival. Old Cromwell incorporated continues to reconstruct buildings from the old town to create a unique historic precinct.
After wandering about enjoying many galleries and noting others enjoying the cafes and restaurants, we agreed this was a delightful attraction for tourists and locals alike. We scored a small bag of fresh cherries from one gallery; the mother of the artists holding the fort and generous with an oversupply of ripe fruit.

After calling into the Information Centre, upgraded since we were last here, but (wo)manned by equally helpful staff, we came north to this large reserve on the western shore of Lake Dunstan where free-camping is tolerated if not encouraged. I fed the local ducks with stale bread I had been reserving for just such a purpose and then we settled down for a quiet late Sunday afternoon, the sun still shining although the doomsayers on the weather channels keep telling us to expect otherwise.

31 January 2015 - Ohau B Canal, Twizel, South Canterbury



It rained all night and was still dismal and wet when we finished breakfast. Our plan had been to drive up to the Blue Lakes carpark and walk up past the Blue Lakes to the viewpoint on the Tasman Glacier moraine wall. From here on a clear day, one has good views of the lower Tasman Glacier and lake, icebergs and the mountains at the head of the valley. This morning we decided we would be lucky to find the car park in the mist, let alone the commencement of the track, although it has probably undergone a massive facelift like the Hooker Valley track. Last time we checked the Tasman Glacier out, the track was a matter of scampering over large boulders; these days hardly up to Health & Safety standards. Perhaps it is just as well we decided to give it away.

We were intrigued to learn about the Alps 2 Ocean Cycle Trail, a trail that starts at Aoraki Mt Cook village, continues down the valley to the airport where one takes a helicopter ride across the Tasman River, continues down the eastern shore of Lake Pukaki, then wends its way on down and around the Waitaki Hydro System, all the way to Oamaru, a distance of 301 kilometres. With the helicopter section, it does make it a rather elite activity; however we would love to do sections of it. Our new motorhome has an excellent bike rack on the rear, but alas our bikes are still back under our house. We will have to return next year, with the bikes, and make sure we tke the opportunity to include a trip to the Tasman Glacier then!

So we left the Aoraki Mt Cook National Park, vowing to come earlier next year, to catch the spikey Golden Spaniards in full bloom and the sun gleaming on the tops of the mountains. As we descended the heights of the alpine area, driving back down the shore of Lake Pukaki, the sky brightened and visibility to the east improved. We did remark on the number of vehicles still heading up to the resort, oblivious of the horrendous conditions ahead of them, and the fact they would see very little today or even in the few days ahead.

We drove south to Twizel, where we shopped in the excellent new Four Square supermarket, dumped our grey water and did a load of laundry at tourist prices: $5 per machine. By the time we had finished there was no sign of rain about at all and the day improved even more after we parked up beside the Ohau B Canal in a specially designated free camping area for NZMCA members. We are one of many motorhomes strung out along the canal not far from the main road, a salmon farm within view and most of our fellow campers with rods set up for their fishy dinner. Chris on the other hand is happy to have television reception and even more, to find that the Pakistan v New Zealand ODI cricket match is being telecasted live on free-to-air.

30 January 2015 - Aorangi Mt Cook, Southern Alps



Despite the fact I woke during the night and spent some time pondering insoluble problems and listening to the crashing of the avalanches in the far off distance, I am sure I slept better than the two girls sleeping in their rental car beside us. What a way to travel! But then I am not in my twenties, so it is hardly comparing apples with apples.
Chris had omitted to set the alarm, so it was well after 7 am that we woke to start our day, and about 8.30 am by the time we set off well-shod in our tramping boots and equally well-equipped with raincoats and refreshments. The cloud was low and soon we were walking through drizzle. Having checked the online weather forecast and seeing that heavy rain was to set in by 10 am, I was keen for us to make a beeline to the end of the track at the Hooker Glacier rather than take all the little detours along the way. There were few ahead of us although we did pass one woman returning; she must have set off at daybreak!


The Hooker Valley Track is an easy grade three hour return walk and much easier than it was when we walked it seven years ago. Not that it ever was challenging, but there were parts where you edged around the cliff above the torrential Hooker River, places you made your way along narrow paths through boulders, and the last part where you could, if you so chose, clamber along the moraine boulders on the west side of the Hooker Lake and across scree slopes. In short it was a charming trail up a gentle valley with plenty of variation and much superb scenery, first across the Mueller River which spews its grey moraine stew down toward the Tasman River, over scrubland, then across the similarly fierce Hooker River just before it empties itself into the Mueller Lake. The track continues up the Hooker River, below the eastern side of Mt Sefton until one reaches the Hooker Lake, over which the high peaks of Mt Cook stand sentinel. It is one of the most popular walks in the park, encouraging all but the old and infirm to enjoy this alpine beauty.
However, we were disappointed that the track itself was now so manicured and almost clinical. We debated about where and what, drawing on our memories and both agreed that there appeared to be new bridges and rerouting of the more interesting parts of the track. There are now many many metres of boardwalk and apart from a few steps at the commencement of the track before the first swing bridge, one could push one of those heavy duty baby buggies all the way to Lake Hooker and back if you were built like a rugby prop-forward.

Later we did some research to see what really had been done and while we were unable to ascertain final costs and dates, we did come upon a media release by the Department of Conservation dated March 2010 where they detailed their plans:

The upgrade will take place over three years:
  • Stage one would cost around $1 million dollars, this simply to cover the plans, designs and resource consents for two bridges, a new 400 metre long section of the track and a new viewing area at Hooker Lake.
  • The track sees around 60 – 80,000 visitors a year and most make it all the way to Hooker lake.
  • The bluff section had a long history of rock fall. Just the previous winter a number of people were trapped behind a rock fall. A new swing bridge would avoid the bluff section.
  • The track would now end on the eastern side of the lake; a new swing bridge would divert walkers away from the outlet of the lake. It would also offer a better position from which to view the lake and the terminal of the glacier.
  • Planning, detailed design work and all consents would take place in 2010/11. Stage two would involve tendering the work and the construction phase of the project would occur in sections to avoid track closures as much as possible, from 2011 – 13. The completed project was expected to cost $1.6 million.
  • The media release concluded by the liaison chap saying: “Our hope is that we will manage the risks of an extreme alpine environment as much as possible, without “cotton-wooling” the experience and it should be a better experience for it”.

Well, we prefer to be less “cotton-wooled” than the upgraded track offers, however we did enjoy our walk, despite the rain, despite the modified track and despite the fact we were unable to see Mt Cook apart from a peak of a side ridge from time to time. Fortunately we had had superb views of this majestic mountain yesterday and also when we last did the walk.

Again we realised that we were too late for the wild alpine flowers and left only the sad or tired bent stems of earlier glory; the alpine daisies, the Golden Spaniard, and a myriad of others who only teased us with their remnants. The birdlife in the low scrub as we set off was wonderful, but much more subdued as we returned; the rain and bludgeoning tourist crowds were enough for any self-respecting bird to take refuge for the rest of the day.

Up at Hooker Lake, we were soon joined by dozens of French tourists and a smattering of Germans, further back toward the camp, guided groups of very polite Asians. The English speaking Kiwis and others were still struggling out of their beds or thought better of setting off into the mountains under low cloud.

We were back within two and a half hours, the return journey quicker because of the worsening weather. Our immediate neighbours in the car were still sitting in the front seats contemplating their day and the grumpy chap in the large hired Britz motorhome beyond was no happier than yesterday; he has done serious damage to the satellite dome on the roof, and if travelling with an infant were not already proving to be too much fun, that would have surely finished it off for him. Both parties left soon after we finished our lunch, as did many others. There seems to be little regard for checkout times at this camp.

Our afternoon has been spent relaxing. I am about to assemble a fish pie, an excellent dish for such a wet day.
