Before you go into the outdoors, tell someone your plans and leave a date to raise the alarm if you haven't returned. To do this, use the New Zealand Outdoors Intentions process on the AdventureSmart website. It is endorsed by New Zealand's search and rescue agencies and provides three simple options to tell someone you trust the details about your trip.
Tararua Forest Park is renowned for its changeable and wild weather, particularly on the open tops. Much of the terrain is rugged, so trampers should travel prepared. Overnight parties should always include experienced trampers.
