Maintenance Status

Top Trent Hut is designated as minimal maintenance. The the tracked and poled route to it over Trent Saddle from the Haupiri valley remains fully maintained. Access up the Trent valley from Mid Trent Hut is untracked, aside from a short section providing access up from the River to Top Trent. In September Paul Reid of Permolat along with with some volunteer friends organised a major working bee at the Hut, funded by the new High-Country Consortium. DOC kindly backloaded the materials in for the project. In December of this year Paul received some additional funding to finish off this work. Hopefully this will take place sometime this summer.

Location

Ahaura Catchment. Grid Ref: NZTM2000 E1504410/ N5271863. Topo Map BU21. Altitude 865m. Top Trent Hut is located in the head of the Trent River, which is a tributary of the Ahaura. The Hut is on the TR of the valley just above a large shallow tarn, probably the "Lagoon" from which it derives its name. Kiwi can be heard calling around the tarn on dark and there is a fair bit of deer sign in the locality. Chamois are often encountered here on the tops. The bush around the Hut is montane forest with a lot of big old broadleafs, mountain holly, pink pine and pahautea (mountain cedar). There is a tiny patch of beech just above the western end of the tarn. The Top Trent hutbook goes back to 1992 and averages around three entries per year, a ratio of one fly-in to every two foot parties. We were the only visitors in 2011. In 2012 there were no overnight stays, but a DOC Greymouth person dropped in while going Mid-Trent from Elizabeth Hut. There were a couple of visits in early 2013.

Access

Top Trent Hut is most commonly accessed from the Haupiri valley over Trent Saddle, and can be done fairly comfortably in a day from the Haupiri roadend. The Haupiri route starts at the end of Heaphy Road which crosses Gloriavale Christian Community land and permission is required from them to do this. The last section of the road is fairly rough with numerous small fords, but is OK for 2WD as far as the carpark at O’Shanessy Flat. A high-axle 4WD might get you another kilometre upvalley. The lower Haupiri is easy travel, mostly grassy flats with a few short sections of boulderhopping. The River can be crossed and recrossed. Cone Creek can be a bit tricky to cross and wouldn't be fordable after heavy rain. There is a concreted-in hot pool 50m up the Haupiri track from the Cone Creek confluence. The track continues up the TL of the Haupiri to Elizabeth Hut, around three hours from O'Shannesy Flat. From Elizabeth Hut the track crosses the TR branch of the Haupiri and climb/ sidles up into the head of the TL branch. It is well-marked, but overgrowing in places with some big patches of windthrow below and above the sidecreek with the waterfall (E1500859/ N5272527). The track crosses to the TL of the Haupiri in the sub-alpine zone and snow-poles and cairns mark the route above the scrubline. From Trent Saddle the route drops into the upper TL basin of Trent, then climbs up around two small gorgy sections which are cut and poled through the alpine scrub. The track drops back into the River and crosses to the TR at E1503658 N5271675, and sidles for a kilometre through the montane forest to the tarn and Hut. Allow three hours from Elizabeth Hut to Top Trent Hut.

The route to Top Trent Hut from Mid Trent Hut is directly up the River. Access to the lower Trent valley is via the Tutaekuri valley and Waikiti Downs. Permission to cross the farmland there is from the Farm Manager Terry who lives in the cottage, not the main house; Ph 03 738 0599. The farm road gates weren't locked at last report and it's no problem for access for trampers or hunters, despite what the gate signs say. There has however been some conflict recently between the Farm owner and DOC. It is open river travel up to Mid Trent Hut and from here up through the Trent Gorge is fine-weather-only. The route is untracked, apart from a short section providing access up from the river to Top Trent Hut. The Gorge section is enjoyable, but involves at least fifty crossings and river edge wading through a series of tight little gorges. From the Waikiti Downs parking area to Tutaekuri Junction allow 2.5 hours, from Tutaekuri junction to Mid Trent three hours, and 4-5 hours from Mid to Top Trent.

There is space for a helicopter to land near the big tarn.

Type

Top Trent is an NZFS S81, four-bunk design with open fire, built in 1960. Peter Robins recalls walking up there to replace the then-rusting fireplace around 1965, however the fireplace and chimney were removed completely at some point later on. The bunks are wire netting on wooden frames. There are mattresses. The Hut is lined and there is a narrow sky light. There is no toilet and water is from a small creek 30m up the Mt. Dixon tops track. The Hut has an interesting welcome sign on its outside wall, taken from a line from Dante's "Divine Comedy."

Condition

DOC repainted Top Trent Hut inside and out in 2003 and dug a drain across the grass area in front of the door. Some bracing was placed between the piles and bearers and one pile was replaced with a block. The working bee in 2015 replaced three piles, sections of some of the bearers, and the skylight. The bottom plate and top plate, some flooring, dwangs and studs were replaced on the South wall, and some short sections of joists were double-braced where they had rotted out. The interior ply panels on the ceiling in an area close to the skylight were removed, along with a section of corrugated iron. Three new rafters, a new centre board piece, a top plate support, a new section of top plate and purlins were installed. A purlin was replaced and a rafter support installed. The eastern door stud, door jamb and bottom plate were replaced. New hex head screws replaced lead head nails for the door bolt. The hut mattresses were scrubbed and sections of the flat iron walls were securely reattached using screws and sealed. The hut roof was spot sprayed with a rust killer product. It was discovered during the work that the hut's roof ridgeline was shot and needed replacing. Unfortunately this wasn't known beforehand and the materials weren't on site to do this. The track from Trent Saddle was recut and marked, along with the track up from the River to the Hut, and the Mt. Dixon tops track. Many thanks to the work crew; Paul, Emma Richardson, Kevin Bolitho, Neroli Amyes, Martin and Kerry Clapham, Alan Jemison and Geoff Spearpoint.

Routes

An old NZFS track onto the Mt. Dixon tops starts at the door of the Hut. and provides very quick access to the tussock. It was recut and marked by Permolat people in 2015. in good condition. It sidles downriver across the terrace initially, then veers up the spur on the TL of the first side-creek downsteam from the Hut. It follows the spur all the way up to the tussock, emerging in the open around 1140m contour. The gradient flattens briefly on a section of ridge with three snow stakes and a few small tarns. The track peters out after the third snow stake at the bottom of a 100 vertical-metre band of low alpine scrub. This is reasonably easy to push through, with the odd open tussock patch. Once in the open tussock travel is easy and straightforward up onto the crest of the Range. There are some   cairns in the tussock leading down towards the top of the track.

There are a number possible crossings into the head of the Trent from the Taramakau Valley, including one described by Frank King up the spur on the TL of Dixon Creek. A fairly well-defined deer trail leads through the bush to the open tops opposite No. 4 Hut, and from here it is an easy traverse over points 1585m and 1600m and down the tops track to the Top Trent Hut. The range is also traverseable right along to Trent Saddle. Frank says most of reasonably defined leading spurs in this area are worth checking out as routes.

There is a high saddle into the Waikiti from the head the big side-creek 800m upriver from Top Trent. The creek has three waterfalls in its lower and mid portions that can be avoided by climbing up the tussock faces on the TL. Sidle back into the head of the creek above the falls. No information is on hand regarding travel in the upper Waikiti, or how long it would take to get down to Waikiti Hut.

Repairs needed

The ridgeline on the roof still needs replacing and this work is planned for later this summer. A toilet would also be a good addition.
