A drone has been seen flying above Hagley Park near one of the mosques at the centre of the Christchurch terror attacks.
Police ask that anyone operating a drone cease this immediately.
“We are responding to try to identify the person responsible and have the drone brought down,” police said in a statement on Sunday morning.
Drone activity has the potential to stop all helicopters responding to the Christchurch terror attack, the statement said.

“Police would remind people there is currently a no-fly zone in place and the penalties for someone caught breaching this are severe.
“Our priority is to ensure the helicopters can continue working safely.”
On Friday, dozens of people were shot and killed at two mosques in central Christchurch. By Sunday morning the death toll was 50, with another 50 injured, two of them in critical condition.
On Saturday morning, Brenton Harrison Tarrant, 28, appeared in the Christchurch District Court on one charge of murder. Police say more charges are likely. He has been remanded in custody without plea until April 5 at 9.15am.
