Massey University's aviation school is warning people to stop shining lasers into planes at night because it could cause a pilot to crash.
School of Aviation chief executive Ashok Poduval said the lasers could cause temporary blindness.
"When they're flying at night you need to keep eyes adjusted to darkness and not have any bright lights around you, so when suddenly there's a flash of light your night vision is either completely reduced or completely removed."
