The Brook Waimarama Sanctuary (“Sanctuary”) is an initiative built upon strong community involvement to create a pest-free wildlife sanctuary near the Nelson city centre, with a 14.5 km long pest-proof fence and an area of over 690 hectares. Nelmac recently completed the track upgrade to the Sanctuary’s circular visitor track to make it suitable for disabled visitors (“Easy Access Path”) and further advance its role as an eco-friendly destination for Nelson’s residents and tourists.

Nelmac’s upgrade work included edging and surfacing 1,220 metres of track, installing extra drainage and reprofiling some slopes to decrease steep gradients. It also included concreting the area around the pedestrian gate into the sanctuary, car park surfacing, installing retaining walls and stabilizing gabions. The terrain and sensitive ecological requirements required strong technical expertise and sound judgement held by our experienced Tracks & Trails team members, including to address areas where asbestos water pipes had been removed close to the stream and to ensure that no pests (including mice) entered the sanctuary during upgrade work.

Key to this project was the creation of a Grade 3 standard track to connect the much loved Involution and Barnicoat Trails. No design or alignment was specified for this track, just a budget, a start and an end point. The rest was left to the skill and expertise of our in-house design and implementation team.

This project required us to:

  • Identify the best possible line to meet the required gradient
  • Cut the initial track line by removing existing vegetation
  • Use of a 1.5 tonne digger to form the track
  • Use existing onsite materials for track surfacing
  • Install suitable drainage methods to deal with the high rainfall that the area can experience

Upgrade of the Dun Mountain Trail

Upgrade of the Dun Mountain Trail (from Copper Mine Saddle to South Branch River)

Realignment of existing track to meet gradient requirement for cycling and improve surface for walking.

Ongoing

Nelmac has been contracted to upgrade the entire Dun Mountain Trail over several years, carrying out the work in stages to avoid interruptions for users whenever possible.

The section of upgrade from Copper Mine Saddle to the South Branch River involved adjusting the existing track, which was extremely rough, to meet the standards of New Zealand’s Cycle Trail network. At the same time, we were able to improve the surface for walkers who also have access to the trail.

Using equipment ranging from a 1.5 tonne digger right down to various hand tools, the work included installation of drainage swales, box culverts and cut off drains, installation of rock retaining and rock placement for stream crossings. When planning the new route, our experienced track cutters had to consider the line and gradient and worked hard to minimise vegetation loss and disturbance .

Given the high rainfall the area can experience, ensuring effective drainage was a critical consideration to ensure the longevity of the track surface.
