Maintenance Status

The current Pfeifer Biv was built in January 2008 to replace a dilapidated predecessor built by the NZFS in the early 1960's. The new structure will be fully maintained by DOC Arthurs Pass. The access route and track up Paratu Creek and from Waharoa Saddle to the tussock was for a while, the domain of DOC Hokitika. They may have done a bit of marking and possibly trimming in Paratu Creek, but the most recent work on the Saddle - tussock section was done by Frank King and Honora Renwick of Christchurch. The route/ track is now officially in the hands of the community, and whosoever desires to take it on board.

Location

Taramakau catchment. Map BV20. Grid Ref: E1490868/ N5260180. Altitude 1295m. Pfeifer Biv is located in a tussock basin on the Aicken Range, more or less directly above Lake Kaurapataka. The small creek adjacent to the Biv drops over the lip of the basin and down a vertical face into Pfeifer Creek. The tops in the vicinity are relatively easy travel, and dotted with small tarns and numerous good camping spots. There are spectacular views from the Biv out over the Taramakau valley to Mt. Alexander and the Kaimata Range. Kiwi can be heard in the basin after dark. Pfeifer Biv is an overnight tramp of moderate difficulty and currently receives around 20 visits per year.

Pfeifer Biv route

Access

Pfeifer Biv is usually accessed from the Deception River via Paratu Creek and Waharoa Saddle. From the Deception carpark on SH73, cross the Otira footbridge and head up the TR of the Deception for around one kilometre. Veer off from the River and head East through a patches of regenerating bush and farmland to Paratu Stream. Head up Paratu Stream taking the TR fork at the 560m contour. The fork narrows and becomes a dry watercourse further up. Follow this up through the montane zone to Waharoa Saddle. The Saddle has an open scree at its top with views of the Taramakau and the Pfeifer tops. A track leads up the ridge from the Saddle through the alpine scrub to the open tussock. It was recut by Frank and Honora in 2007, given another trim by me in 2012. Some current feedback on its condition would be helpful, although it should still be OK.

Once in the open the trail goes up and over a knoll, then climbs to flat area at the 1300m contour. There is a reasonable sized tarn at 1364m, and the spur is followed from here to a rocky knoll at 1460m. Drop East from here down the edge of a rockfield and over a series of benches into the tussock basin below. Follow the fault scarp along lip of the basin, and up and around the next spur into the second basin where the Biv is located. If you don't have GPS, fine weather and good visibility are essential for the tops section. Allow 4-6 hours for the journey from the Highway to Pfeifer Biv.

Type

The original Pfeifer Biv was a B55 design built by the NZFS in 1962. It wasn't maintained after DOC took over from NZFS in the 80's, and became increasingly dilapidated over time. The new Biv is a good example of an over-the-top, impractical, and ridiculously expensive small hut design, constructed to building code standards that are totally unnecessary for basic high country shelters. It is mounted on a steel sub-floor and secured with tie downs. The Biv is lined, has a double-glazed window, two sleeping platforms with mattresses, and a cooking bench. A large and ostentatious toilet, half as big as the Biv itself, stands like a sentinel nearby. Water is from some small tarns just below the Biv, or the creek.

Condition

The design which Pfeifer shares with two other new structures in Arthurs Pass fails to strike a good balance between light, ventilation, and insulation. The larger of the windows and glassed door are South facing and the interior is shady and damp with condensation. It probably doesn't dry out at all during the colder months. The biggest pane of glass on the door is not double glazed. There are already large areas of mildew developing on the interior North and end walls. This never happened in the draughty and poorly insulated NZFS models. Maybe those simple iron shells insulated with tar paper and chicken wire weren't such a bad idea after all. Another technological advance that hasn't fared well at Pfeifer is the polystyrene underfloor insulation, which Kea have discovered, methodically shredded into thousands of small particles, and scattered like hailstones around the Biv. The ties downs were very slack in November 2012 and it was a hell of a job undoing the tangle No. 8 wire twisted and threaded through the turnbuckles, so we could re-tighten them. The wire was probably put there to stop people adjusting them. If so, why? The NZFS used to wrap the turnbuckles in denzo tape and leave a spare roll in the Hut so that passers-by could make adjustments when necessary.

Routes

The Aicken Range tops are easy travel in both directions from Pfeifer Biv in good conditions. Mt. Pfeifer is a 45 minute scramble when snow-free, and has great views. Access down into Pfeifer Creek is possible from the first basin East of the Biv basin. It is a relatively easy sidle around, with a bit of altitude needing to be gained to stay above some scrubby bluffs. Once in the eastern basin, head through patchy scrub along a small scarp at the basin's lip onto a bench. Two cairns here mark the start of the route which is down the steep scree below. The scree joins another on its TR further down, and there is a permolat marker here for those coming uphill. Continue down the scree to a small-side branch of Pfeifer Creek. There is a red permolat marker on a tree in Pfeifer Creek just below where the side-creek enters. Boulderhop from here down to the Lake Kaurapataka track.

The NE spur of Mt. Pfeifer can be used as a route to the saddle at the eastern end of Lake Kaurapataka, but is a fairly long scrub and bush-bash, and rough going in places.

A fine weather alternative for getting off the Aicken Range for the more experienced, is down Tutu Creek into the Lower Deception. Access into the head of Tutu Creek is down a scree immediately South of point 1591m. The top of the scree is vertical and unstable and needs to be accessed from a steep tussock rib on its TL. Sidle off the rib onto the scree around the 1500m mark. The scree is narrow and steep initially with loose rock, but becomes broader and more stable lower down. It enters Tutu Creek at the 700m contour, and this is followed down to the Deception River. Follow the Deception valley track form here down to the Highway. Allow 3-4 hours to reach the Deception carpark from the Biv.

Repairs needed

The Biv ideally needs to rotated 180 degrees so that the door and side window are north facing. Whether the additional light and warmth would solve the mildew problem remains to be seen. If DOC decide to replace the underfloor insulation (I suggest they don't bother), then it would have to be kea-proof. A roll of Denzo tape could be provided for the tie-downs.

Provisions on site

One aluminium basin, and a hearth brush and shovel.
