Those effects are distraction, glare, afterimage, flash blindness, and even persistent or permanent visual impairment, and can affect their ability to fly safely.
"This is especially dangerous during critical phases of flight, landing and take-off.
"This issue is particularly concerning for us due to the fact our aircraft are conducting training flights, including solo night flights without an instructor on board.
"Although in most cases laser strikes only result in a distraction for pilots, it could result in an accident should the effects on the pilots' vision be severe enough."
Smith said the latest strike on March 15 was caught on video.
"This requires a community response and a collective attitude that this is not 'cool' behaviour in the very least.
"NZ Police have been informed obviously but any help the community can provide is much appreciated."
