A rescue plan has successfully dropped off more supplies to Scott Donaldson as he battles his way across the Tasman in an attempt to be the first to make the solo trip by kayak.
The Hamilton multi-sport coach left Coffs Harbour in Australia on 29 April this year but has been hampered by technical problems.
The 43-year-old was running dangerously low on food and water last week, when a rescue pilot and his son made the 600km round trip to drop supplies.
Pilot John Funnell took off on a second flight from New Plymouth on Thursday morning drop more water and food and a repair kit to the kayaker.
The drop was planned to take place later this week, but Mr Funnell said a shortage of water and adverse weather have brought forward the timetable.
Scott Donaldson still has about 250 nautical miles to reach New Plymouth, taking at least 10 more days.
