The Civil Aviation Authority is doing more to catch people who target aircraft with lasers.
It has issued a safety checklist to pilots who are dazzled, distracted or disorientated by laser beams.
The authority says pilots affected by a laser strike should inform air traffic controllers, who can then alert the police to try to identify offenders.
So far this year there have been at least 15 laser incidents reported to the Civil Aviation Authority, nine of them in Auckland.
In 2008, there were 56 incidents across the country.
The Airline Pilots' Association plans to lobby the Government for tighter controls on the sale of lasers and tougher treatment of offenders.
