Police say it will be weeks rather than days before they decide whether to lay charges over the fatal shooting of a hunter in the Wairarapa.
The post-mortem on the body of Auckland's Cam McDonald, 29, was completed in Palmerston North on Monday and his body had been released to his family, police said on Tuesday evening.
It is believed Mr McDonald was shot dead by the member of another hunting party while in the Aorangi Forest Park, near Pirinoa, southwest of Martinborough on Saturday.
Police have spoken to the hunters and have said criminal charges are likely.
However, Detective Senior Sergeant Sean Hansen says that a full investigation will take some time and then police will get a legal opinion regarding potential charges.
"This is likely to take some weeks as opposed to days," he said.
Earlier this month Reuben Burke, 24, admitted careless use of a firearm after he mistook his friend Dougal Fyfe for a deer and shot him dead near Wanaka last year.
In 2010, Andrew Mears mistook teacher Rosemary Ives for a deer and fatally shot her as she cleaned her teeth in the dark at a campsite near Turangi.
He was sentenced to two-and-a-half years' jail but was released after 11 months.
