The Department of Conservation and WorkSafe are investigating the death of a female cyclist on the Mountains to Sea cycle trail in March.
The death happened on March 17. A rescue helicopter was called at 2.50pm, but the woman had died before it arrived.
At the time, police said the woman had fallen off a bluff near the Bridge to Nowhere, which is on the Mangapurua stretch of the cycle trail in Whanganui National Park. That section of trail has some fearsome bluffs, including Battleship Bluff.
The grade of the cycle trail there is 3 - moderate. But the trail website warns it should only be attempted by fit and experienced offroad cyclists, and there are bluffs where cyclists dismount and push their bikes.
Authorities have released no further details.
