​In late 2017 Bull Paddock Creek Biv was officially closed after an engineering inspection concluded that the foundations were weak and could fail, potentially resulting in the biv toppling down the hill. Working with the DOC engineer, a volunteer group came up with a plan for a new set of foundations for the biv that would meet an appropriate construction standard. The Backcountry Trust approved funding for the project in Round 9.

The 49 kilometre Wangapeka Track has five huts along its length, two bivs and one historic hut (Cecil Kings Hut). The mid way point is the 10 bunk Helicopter Flat Hut which started life in 1963 as a standard S70 NZFS hut. Over time it has been enlarged and modified to cope with the increasing use of Kahurangi National Park for recreation.
 
In Round 9 the Backcountry Trust funded a modest maintenance project for a retired building team led by Bill Barnett. As part of this it was also decided to reduce the bunks from 10 to 8 to better reflect the use patterns on the Wangapeka and make the hut a little more open and less crammed.

​Back in early Winter 2019 Alastair Campbell got a group together from Permolat Southland to carry out the catch up maintenance on Caroline Hut on the shores of Lake Hauroko in Fiordland National Park.
 
The hut was built in the 1960s by a group from the local NZDA Branch using native timber from the local Tuatapere Mill. Over time the hut has developed a few issues including a number of floor joists that had been badly affected by borer and had subsequently fractured. The roof was also leaking.
