Coastal parts of the Heaphy Track have been damaged by high tides and storm events, a report by Department of Conservation ranger Ted Brennan to the West Coast Tai Poutini Conservation Board said.
Mr Brennan said the affected areas were the coastal sections of the track at Koura Beach, Nettle Beach and Heaphy Beach.
Kawatiri DOC services manager Bob Dickson said the track was not closed, but sections prone to erosion and sea encroachment had been re-routed as an interim measure to ensure public safety.
Warning signs indicating the need to be aware of high seas and storm events were also in place.
Mr Dickson anticipated work on the track would be underway once final funding was approved, which was expected in October.
The estimated cost of the repairs was $288,000.
He said there was no plan to close the track, however a contractor would need to manage the site to allow public access.
He did not think the work would have any impact on users this coming summer.
