Two people have been arrested after a woman's body was found in a bag in Auckland's Gulf Harbour earlier this year.
The body was pulled from the water by a fisherman on 12 March, sparking a homicide investigation, and her identity has not been revealed.
Acting Detective Inspector Simon Harrison says a woman and a man, both aged 36, were arrested late on Sunday.
The pair will appear in the North Shore District Court on Monday, charged with interfering with human remains.
Police are not ruling out further arrests or charges.
Harrison said police were made aware on Sunday of the two people attempting to leave the country.
He said a search warrant was being carried out at a residential address in Ōrewa in relation to the wider investigation.
"The investigation is ongoing and police are speaking to a number of people at the address as part of our inquiries.
"A scene guard is in place and will likely remain for the next couple of days while the investigation continues."
There would be an increased police presence in Ōrewa, Harrison said.
The body of the woman, who was in her pyjamas, has still not been identified, Harrison said.
"We continue to appeal to the public for any information which could assist us with identifying her."
