The Operation Burnside team have a dedicated email address for anyone wishing to report anything in relation to the inquiry.

"operation.burnside@police.govt.nz is a good opportunity for people to report damage to property or anything else they think is relevant," says Detective Superintendent Brett Kane. "Many people have access to a computer and this saves time waiting for phones to be answered or messages to be replied to. It doesn't replace the phone but is another avenue for reporting."

"We are grateful to the residents for their patience and assistance," says Brett Kane. "We thank Community Watch volunteers for their assistance.
