An investigation is under way after an Air New Zealand plane was forced to take action to avoid a mid-air collision with a smaller plane.
The incident occurred on the morning of August 28 over Northland.
The Transport Accident Investigation Commission launched an investigation saying an Air New Zealand Q300 passenger aircraft ZK-NES, flying from Whangārei to Auckland, was involved in the near-miss.
A Beech 76 Duchess aircraft ZK-JED, en route from Auckland to Whangārei, was the other plane involved, with both flights being on reciprocal tracks.
“A close proximity event occurred and the crew of ZK-NES took avoiding action.”
