Mystery surrounds the discovery of human remains in the waters of Auckland's Gulf Harbour on Tuesday, with police confirming they're still trying to identify the body.
Acting Det Insp Tim Williams said investigations, which are still in their early stages, will continue on Wednesday.
"The body has been recovered from the water and a post-mortem examination is expected to begin later today.
"Police have finished our enquiries at the scene with our cordons being stood down."
He said officers have spoken with people who were in the area at the time the body was found but urged anyone with information to come forward.
"We would also encourage any residents in the nearby coastal area that saw anything suspicious to contact us.
"People can contact police on 105 or go online to https://www.police.govt.nz/use-105 using 'update my report.' Please reference file number 240312/9837."
The man who found the body told RNZ about the moment he found the human remains.
He described the bag as heavy but easy to move and decided to investigate.
"[I] took the hook out and thought, 'Right, let's see if it's a bag of rubbish and I need to dump it in a rubbish bin or something,'" he told RNZ.
He struggled through "layer and layer" of plastic to open the bag and "lo and behold, a hand appears".
The man told the state broadcaster it looked "like a Halloween-type hand".
