By Friday last week, a team from the Hawke's Bay CIB had established that Mr Paludet and his vehicle were likely in the carpark from Wednesday, January 10, 2018.
They were first alerted to his disappearance when local residents called police after noticing a build-up of rubbish and his car seemingly abandoned.
He was last seen in the carpark early in the evening on Friday 12 January.
Searches of the area, both on land and in the surrounding water, had failed to locate Mr Paludet.
Detective Senior Seargeant Martin James said police were continuing to liaise with his France-based family who were increasingly worried about him; his lack of contact with them described as completely out of character.
Yesterday one policeman was stationed at the Domain carpark in Haumoana speaking to residents after police urged anyone to come forward to speak to them in person.
