Some hotel and motel owners had also been caught out by the man. They included two Tauranga hotels and apartments, after he pre-booked accommodation using fake company emails, said Detective Sergeant Darryl Brazier of Mt Maunganui CIB.
The scam was not realised until the owners sent the account payments to the email addresses, which were "legitimate email addresses but they are not the business addresses they purport to be".
The man also used names of real employees of the company.
"He comes across as a very believable and plausible character," Mr Brazier said.
"He regularly uses stories, such as his mother has recently died or is extremely ill, and tries to obtain sympathy from them.
"He's coming up with all sorts of sob stories."
In another case, the suspect had stolen a white Nissan Tiida from a Mt Maunganui rental car agency and then sold it to an unsuspecting buyer in a cash deal. The buyer who was told "all sorts of reasons" why the money could not be paid into an account only discovered it was reported stolen after attempting to register it.
"I'd say he's no stranger to this. He certainly has a lot of confidence in his offending," Mr Brazier said. "He's putting a lot of thought and time into his offending."
Mr Brazier said there may well be other cases police are unaware of.
"There are a number of crimes starting to tally up and obviously need to get our hands on this guy before he rips other people off," he said.
Kris Stamatakos, of the Tauranga Motel Association, said moteliers had been warned about the recent spate of dodgy dealings.
"Motels should just take credit card details, regardless of if it's a company, and verify it," he said. "It's the one thing that a lot of motels don't do.
