Emergency services have rushed to an "incident" in Christchurch, which RNZ understands is a sudden death.
Police said they are responding to an incident at an address on Grassmere Street, Papanui.
Hato Hone St John said they were called to the address at 1.15pm on Thursday. They said one ambulance and one operations manager responded.
A reporter at the scene saw several uniformed officers travel down the driveway at the address, but some officers had since left.
Police said further information will be released when we are in a position to do so.
