An air drop of vital supplies will be made to a trans-Tasman kayaker first thing tomorrow morning.
Scott Donaldson, 34, is attempting to cross the Tasman Sea by kayak.
The Rotorua man left Coffs Harbour on the NSW coast on April 19, and is hoping to land in New Plymouth.
Although an air drop was scheduled for Saturday, due to a broken rudder, Donaldson is running low on water and the drop was pushed forward.
Rescue pilot John Funnell, who is based in Rotorua, said a drop was planned for first light on Thursday.
