A record number of laser strikes on aircraft last year underlines the need for tough new controls coming into force tomorrow, Associate Health Minister Jo Goodhew says.
There were 119 strikes in 2013, the highest ever in a calendar year, and up from single figures in 2006.
"These strikes can also cause temporary flash blindness, which poses a serious risk to pilots," Mrs Goodhew said. "The Civil Aviation Authority reports five laser strike incidents on planes already this year - the most recent affected an international flight landing at Auckland.
"High-powered laser pointers can also cause eye injuries, even blindness, and skin burns. ACC accepts around 10 claims a year for these injuries."
New controls on hand-held laser pointers with a power output of more than 1 milliwatt come into effect tomorrow.
