There will be a washing station for boots, other gear and vehicles at the walk's start to ensure the event does not introduce kauri dieback disease into the still uninfected Puketi Forest.
A $50 fee will get walkers on the track and give them a year's membership to the trust which has been in operation for 11 years. Each $50 paid will fund predator control over 1ha for a year.
"We believe this is one of the best one-day walks in Northland," Ms Beaver said.
"We have a core area of 650ha with rat, stoat and possum traps and a larger area of 1700ha with stoat and possum traps.
"We employ part-time trappers and also have volunteers to service our trap lines. As you can imagine we are always looking for ways to fundraise, hence this walk."
Under the trust's care, kiwi numbers have increased during the past decade, as has the number of North Island robins. Two years ago, kokako were translocated to Puketi and the trust is hopeful those birds will breed successfully this summer.
The 21km Forest Traverse starts on the east side of the forest and ends on the southwest side at Forest Pools. It follows the old Pirau Rd logging route, then descends down the Pukatea Track to the Waipapa River.
After 2.5km along the river, the track widens and follows the remnants of a road intended to link Hokianga with Kaeo but was abandoned by crews, partly constructed, in the 1930s.
