Update Friday 29 June, 6pm
Trig Road South, Waihi is open to traffic in time for the weekend.
There is still work to be done, and a 50km/hr speed limit is in place, but motorists can once more take the Trig Road South way home after a large tomo caved in underneath the road more than a week ago.
Work to clean up the site and reinstate fencing will continue on Monday. The road will be left unsealed for a month and the speed restriction will stay in place to allow for settling and monitoring of the new section of road.
Thank you for your patience and understanding while we've carried out this work.

Trig Road closure due to large tomo
Trig Road South, Waihi, will remain closed near the intersection with Mathers Road for several days due to a large tomo which caved in underneath the road last night, leaving a hole approximately 1.8m wide at the surface and extending 4m - 5m deep under the road.
The tomo was discovered by a local contractor transporting farm machinery. The area was immediately coned off and manned by locals until Council staff arrived to officially close the road and safely secure the site.
Deputy Mayor Toby Adams, who is also Council’s roading and transport portfolio holder, visited the site this morning to check on progress.
“I’d really like to acknowledge the speed at which both the community and Council staff responded to this incident to ensure no one was at risk at any point. It was dark at the time, but thankfully no one was hurt due to the quick reactions of all involved,” he said.
Investigations are now underway to determine the cause of the collapse and plan remedial work.
Hauraki District Council Group Manager Engineering Services Adrian de Laborde said a series of tomos have been found on both sides of the road, as well as the one beneath it.
“Water has run beneath the culvert and formed an underground watercourse that has caused these tomos over time. Recent heavy rain in the area has exacerbated the problem,’ he said.
He says work is continuing to determine the direction and extent of the underground flow of water and a bigger culvert will be installed and realigned over the next few days to prevent a recurrence of the problem.
“We’re aware this road is often used as a shortcut between Tauranga and Whiritoa. Unfortunately, it’s unlikely it will be reopened this week. We apologise for any inconvenience and thank motorists and local residents for their patience while remedial work is carried out.”
