The Civil Aviation Authority has finished an aircraft examination of a microlight that crashed on Sunday killing two people.
The wreckage was discovered in a paddock in Kaipara's South Head district about 2pm on Sunday. It had been reported missing about midday.
Police say two men had been flying from Paraparaumu to Dargaville after attending the Royal New Zealand Air Force 75th Anniversary Show at Ohakea.
The men, believed to be in their 70s, died at the scene.
Dargaville Aero Club flight instructor Murray Foster says the pilot was very good at planning trips and had flown quite a bit - both overseas and in New Zealand.
Mr Foster says the passenger was also learning to fly and had completed a few flights under instruction.
The wreck will now be given to insurers.
