Akaroa police have had to ask for help, after two break-ins at the Jones Bay boat sheds in French Farm.
There's one break-in that's got them particularly confused though, as burglars removed all the items from one of the sheds and replaced them with their own.
Police posted a photo of the shed to Facebook on Thursday, saying it was the second break-in to the sheds between March and December 2017.
"A second shed there has been broken into and the owners' property has been taken, replaced by the burglars'," the post said.
"They've also done a few alterations to the sheds!"
"Contact Akaroa Police regarding items stored in this boat shed," the original owner wrote.
"Return stolen articals [sic] to police," the burglars replied and requested the original signwriters prove ownership of the shed.
Police believe the burglars may not live in the area and are asking the public to call Akaroa Police on (03) 304 1030, if they have any information.
Looking at the items left in the shed, police believe the burglars are likely to own a dog named Bear (or possibly go by the name 'Bear' themselves), like wine and DIY, and use a kayak or boat.
