Mr Hammond's body was sent to the Institute of Forensic Medicine at the Police General Hospital for a detailed autopsy.
His uncle has created a Givealittle campaign to raise money for his family to return his body home to Mahia, in New Zealand's north.
'Our much loved son, brother and for so many a friend, Akuhata tragically lost his life while on holiday in Thailand,' he said.
'We are heartbroken by this sudden loss and wish to bring him back to New Zealand so his family and friends can say their final goodbyes.
'The costs involved in bringing him home are significant, and we are reaching out for any support to help make this possible.
'Your kindness and generosity during this difficult time would mean the world to us.
'Thank you for helping us bring Akuhata home.'
