Damage from persistent rainfall earlier in June caused the closure of part of the Bridge to Nowhere walking track.
Department of Conservation Whanganui operations manager Jim Campbell said the Mangapurua Track had been closed to all users from the Bridge to Nowhere to the Trig due to significant slips and damage.
The damage was caused by recent weather events, with substantial rainfall recorded across the region earlier this month.
The Bridge to Nowhere track remained open but Campbell advised people to exercise caution as there was damage to some barriers and slips that needed to be crossed.
Repairs to the track would be dependent on weather, the availability of resources, staff and contractors and the relative priority of these tracks for DoC, Campbell said.
