A property in Levin has been attacked by an arsonist twice in the last two weeks.
Police are now looking for a distinctive blue petrol container used to set fire to the Stuckey St house.
The petrol can was ignited and left next to the house in the early hours of yesterday morning.
The house suffered moderate damage and police said it was lucky no one was injured or killed.
Police said the same property was targeted on May 6.
