The 13-ft fibreglass caravan - which Fletcher named Duane - would be easy to steal because of its small size, but would be hard to hide because of its unique look, Fletcher told the Herald.
"It's that rounded kind of a shape with a full kitchen and two singles or a double bed. It's very, very light and stylish."
Anyone who had a vehicle with a tow bar could have taken it, he said.
He reported the theft to the police today and said he thinks the theft was planned rather than opportunistic.
"[Seaside Ave is] not a street that you drive through to get somewhere else so to speak. I suspect they saw it a while back and decided to come back and pick it up."
He said he was unsure why someone would want to take it.
"One possibility is it's in a garage somewhere being spoiled with a horrible spray paint job. Or else it's, I don't know, gone up north or to the Coromandel or gone bush somewhere. It is possible that it's just down some side road up north or down south."
Duane is registered and has some distinctive features that Fletcher would be able to recognise if he saw it.
"At the moment it's got a little stone hole in the front windscreen that's got a bit of tape over it. It's got a little ding that the previous owner put in it in the right hand corner even if it had been painted.
"It's got the curtains in it that I sewed from fabric that I bought in Patea from a second-hand shop and things of that sort."

She said police were making inquiries into the theft.
