An RNZAF Iroquois Helicopter will today search the northern end of the Coromandel Peninsula for the missing aircraft which took off from Ardmore airfield on Tuesday.
Daroish Kraidy's aerobatic biplane disappeared from radar detection shortly after take-off on Tuesday morning, and neither he nor his homemade plane has been seen since.
Rescue Coordination Centre New Zealand (RCCNZ) Mission Coordinator Neville Blakemore said the area had not yet been covered by search teams looking for the 53-year-old from Mt Wellington.
The Iroquois was expected to be airborne around 9.30am.
"At the same time, we will be doing a comprehensive review of the search and all the information received by the public to assess what our next steps should be," Mr Blakemore said.
