Kapiti-Mana Police want to locate 38-year-old Randall Ure after a warrant was issued for his arrest for arson and burglary.
Two weeks ago, a Doncaster Terrace residential property was set alight and Police believe Mr Ure is responsible.
Police believe he is living rough in his red 1990 Toyota Corona station wagon, registration OS4934, in the Porirua area.
He is a disqualified driver and should not be on the road.
In previous Police interactions, Mr Ures behaviour has been unpredictable and he should not be approached.
Anyone who sees URE or his vehicle should contact the Porirua Police as soon as possible on (04) 238 1401.
