A spike in thefts from trailers means some people need to be more vigilant about security, police say.
Thefts from trailers were up across greater Wellington in recent months, according to the police Car Squad.
"Trailers are vulnerable to theft as they are less likely to be afforded the same protection as motor vehicles," said Constable Brittany Allan of the District Car Squad.
"Trailers are often left unsecured or poorly secured on residential front lawns or driveways and can be stolen relatively quickly and quietly," Ms Allan added.
Wellington Police said a person was arrested on Monday in Stokes Valley for the theft of a trailer.
