Neighbours told Newstalk ZB this morning they heard noises last night but put it down to fireworks.
One woman said she went back to sleep after the noise but realised it was not fireworks after her son woke her to say police had come to the street.
Police are appealing for people who know the deceased or have information about what happened to contact the Manukau Police Station on 0508 422 443, or if they wish to remain anonymous to contact Crimestoppers on 0800 555 111.
Counties Manukau Police are expected to release more information this morning.
