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.
The new controls, under Health and Customs legislation, restrict access to those with a legitimate reason, such as astronomers.
"From March 1 anyone wanting to import, sell or acquire high-powered laser pointers will need to apply to the Ministry of Health for approval. Applications are free, and can be made through the ministry's website," Mrs Goodhew said.
Lower power devices, like those used for pointing during presentations, will not be affected.
The controls do not apply to more sophisticated laser devices such as survey instruments or rifle sights.
