The search for missing Indian student Mandeep Singh has been called off.
Acting Detective Senior Sergeant Marcia Murray said the search in central Auckland had failed to provide any further lines of inquiry into what happened to the 20-year-old student.
"Police do now know that Mandeep was seen on a pier in Queens Wharf just after 4am on Sunday morning and was alone at the time," she said.
"So, at this stage, unless further information is received, we are not treating his disappearance as suspicious."
Police said the matter would now be referred to the coroner.
Mr Singh, a culinary arts student from India, went clubbing with three flatmates in the early hours of Sunday morning before they lost contact with him in the Bungalow 8 nightclub at the Viaduct Harbour about 3am.
A police dive squad searched the Viaduct area this week but did not find Mr Singh.
