"There are no dental or other records of Mr Singh available in New Zealand and we have to obtain that material from his family in India.
"That process will take some time."
Det Snr Sgt Scott says the formal identification process is very important and has to be finished conclusively.
"It is not slowing the inquiry down," he says.
A dozen detectives from out of town are still in Gisborne to assist with the inquiry.
"Information from the public has been coming in and we are working through that."
Det Snr Sgt Scott says police hope people will keep coming forward with information.
A spokesman for the family of the dead man says Mr Singh's wife and sister-in-law are coming here as part of their grieving for him, and he hopes their privacy will be respected.
The public fundraising appeal for the family has now raised over $1000 since it opened on Tuesday.
