What's happening with the culvert and the road?

Two major improvement projects are taking place on Trig Road North from October 2025.

Road Rehabilitation

A 1.5 km stretch of Trig Road North (from property #45 to just before property #186) will be widened from 4.8 metres to 6 metres, creating a safer and more user-friendly route. The work will include:

  • Significant road widening and alignment improvement (including fencing relocation)
  • Installing stormwater drains
  • Building up the road base
  • Final surfacing

When: Early to mid-October 2025 through to March 2026

Who’s doing the work: HEB Construction

Culvert Replacement

At the same time, we are also replacing an old, corroded culvert, located on Trig Road North around 250m from the Waihi Beach Road intersection. Its replacement will be a new, stronger concrete culvert that ensures the long-term safety and stability of the road. As this culvert carries a tributary of the Ohinemuri River, the stream will need to be temporarily diverted to replace the old culvert with the new one.

When: Mid-October to early December 2025 (about 8 weeks)

Who’s doing the work: Ventia
