"What annoys me is it's just not allowed."
Fryer said Nikau St is very narrow. Having the boat parked there means cars can only go single file. He said the vessel looks like a "bloke's fishing boat".
"If you put something wider than a normal car there it just makes it more inconvenient and it's against the law.
"They should actually tow it away and put it in a pound until someone claims it."
Auckland transport spokesman Mark Hannan said they are looking for the boat's owner.
"The trailer doesn't have a registration so we can't track the owner that way.
"Last week we visited and took serial numbers off the outboard to see if we could get a marine shop to assist us to find an owner.
"The next step will be, removing and storing the vehicle, the owner will be required to pay towing and storage fees and a $200 infringement for not displaying plates."
Hannan urges the public to get in touch if they can assist in finding the owner.
