Recent incidents in Morrinsville, Cambridge and Hamilton would suggest some people think directing a laser pointer towards aircraft is a fun thing to do, says police.

"Police wish to highlight the dangers of such actions where it could lead to the potential loss of an aircraft or someone's life.

"We would encourage everyone to report any laser strike to Police, to give us as much information as possible to attempt to identify who is responsible.
