Two pilots were struck temporarily blind by green lasers shone into the cockpit at Wellington Airport.

Acting senior sergeant Andrzej Kowalczyk said a Jetstar flight was preparing to take off at about 8.40pm last night when a green laser was shone at the pilot from the Lyall Bay area.

About 20 minutes later an Air New Zealand plane coming into land also reported a laser strike.

The aircraft - an Airbus A320 and a Boeing 737 - could have been carrying more than 100 people, he said.

Kowalczyk said the offender or offenders were putting the lives of the pilots, flight crew and passengers at risk.

"When is it funny for these people? Is it when the plane crashes or when the people are burning?

"When [the laser] hits at an angle on glass, it completely blinds you. You can't see anything."

The incidents have been handed over to airport police, who will interview the pilots.

Police would like to hear from anyone with information about the laser strikes.
