A teenager has pleaded guilty to aiming a laser at the cabins of three commercial aircraft and the police Eagle helicopter in Auckland earlier this year.
Pravikash Chandra, 18, appeared in Manukau District Court this morning to plead to four charges of endangering transport.
He will be sentenced in September.
The judge has ordered an expert analysis of the type of laser Chandra used, including its legitimate application, where it is purchased from and what instructions come with it.
The judge will also be briefed on the effectiveness of the laser, including its range and illumination power.
