Te Anau-Manapouri Trail trustee and engineer David Boniface inspects the extensive repairs to the portion of the trail closed last month because of a slip near Queens Reach. The full trail is now open again.

A closed section of the Te Anau to Manapouri cycle trail has reopened after being repaired.

An 800-metre section of the cycle trail was closed last month after a heavy rain event caused a slip.

Fiordland Trails Trust member and engineer David Boniface said heavy rainfall in the Te Anau Basin brought about 75mm of rain in a 24-hour period.

The section of the trail from Queens Reach to Balloon Loop Rd has been open only since May and the ground was quite raw, Boniface said.

"When you open it up, you're always going to get occasional slips and slumps."

There were several sections in need of a little repair throughout the 19km trail, Boniface said.

The section with the slip had been repaired and stabilised using gabion baskets, with the trail rebuilt on top of the baskets, Boniface said.

The trail had also been widened from 1.2m to about 2m so it could now act as a passing bay, he said.

The repairs to the section took just over a week and cost about $6000.

To put the figure into perspective the last 9.5km of trail that was built cost the trust $380,000, Boniface said.

On Monday, the trust held a public meeting in Manapouri to tell the community about the next leg of the trail it would complete: from Manapouri to Balloon Reach Rd.

The trust was aiming to start work on the leg in February, Boniface said.

"There's a little bit of money to raise yet and consents to sort out, so there's a little bit of homework to be done yet."

The trust was about $28,000 short to build it, he said.

All that would be left was 4.5km of the road from Supply Bay Rd through to balloon loop Rd, 2.5km of which would go through the national park, Boniface said.

"The cycle trail could not be built through the Fiordland National Park until amendments were made to the park management plan."

While it was physically possible to use the highway until the section was complete, the trust was not looking do that, Boniface said.

"This trail isn't about putting people on the highway; this trail is about giving them an experience along the river and through the forest."
