Police investigating the murder of British backpacker Grace Millane are looking for a shovel believed to be connected to the inquiry.
The 22-year-old disappeared in Auckland on 1 December. Police ended their search on Sunday after finding a body on the outskirts of the city.
Det Insp Scott Beard said the body was found “intact”.
A 26-year-old man has appeared in court in New Zealand charged with Miss Millane’s murder.
Det Insp Beard said he believed the long-handled shovel could be “anywhere between the Scenic Drive and central Auckland areas.”
“Someone may have come across it, picked it up and taken it home.
“We need to speak to that person or anyone who has seen it,” he said.
David Millane, Grace’s father, has flown to New Zealand and visited the place where the body was found.
He took part in a traditional Maori blessing ceremony alongside Grace’s uncle and members of the New Zealand police force.
Investigators are trying to trying to establish a timeline of events leading up to the death of the graduate from Essex.
Officers said they had received “hundreds” of calls about the case.
A “location of interest” was identified on Saturday night, leading investigators to a spot on Scenic Drive – a country road about 12 miles (19km) west of the city centre.
Det Insp Scott Beard said on Sunday that investigators had “located a body which we believe to be Grace” about 10 metres (33ft) from the roadside.
Miss Millane had been travelling alone in New Zealand for two weeks, following a six-week group trip through South America.
Police believe she was killed between 1 December and 2 December.
The 26-year-old man charged with her murder, who cannot be named, is due to appear in court again next month.
