Police divers searching for an Indian student missing for a week from Auckland failed to find any trace of him yesterday.
Srikanth Rayadurgam, 23, was reported missing after he did not return to his sister's home at Mt Albert on October 1.
Police said he was not suicidal, had no known enemies and his disappearance was of increasing concern.
Divers yesterday searched part of Waitemata Harbour, but had not found any further information about where he was, acting Detective Senior Sergeant Joe Aumua said.
"The team searched the area of the harbour nearest to Westhaven Marina from about 10am to 5.30pm in both high and low tides, but to no avail."
Mr Rayadurgam had not accessed his bank account since the afternoon of Thursday October 1, Mr Aumua said.
"Further, his mobile phone, which was recovered along with other personal items at the Curran St end of Westhaven Marina early on Friday the 2nd, has not been used for any out-going calls since the previous evening."
Police had spoken to Mr Rayadurgam's colleagues, family, friends and acquaintances but discovered no clues as to why he disappeared.
Police want to hear from anyone with information, in particular officers wanted to hear about suspicious behaviour around Curran St and Westhaven Marina overnight on Wednesday September 30, Mr Aumua said.
Mr Rayadurgam lived with his sister and had no other family in New Zealand.
He arrived in the country this year to study at the Auckland University of Technology.
