An Air Force Iroquois helicopter will resume the search this morning for an Auckland man's missing biplane.
Daroish Kraidy's home-built aerobatic plane disappeared from radar detection shortly after it took off from Ardmore airfield about 11.25am on Tuesday.
A police launch, divers, helicopters and fixed-wing aircraft have been involved in the search, but the 53-year-old and his plane remain missing.
Rescue Coordination Centre New Zealand (RCCNZ) mission co-ordinator Neville Blakemore said an RNZAF Iroquois helicopter would search the northern end of the Coromandel Peninsula today.
The area had not yet been covered by search teams.
