A spate of wheelie bin fires in a Christchurch suburb has police urging residents to bring their bins in at night.

The majority of the fires have occurred near Waimairi Rd and Greers Rd in Ilam, at night during the weekends over the past two months, Senior Sergeant Stephen McDaniel said.

Properties and vehicles have also been damaged following the fires.

Police are asking residents to remember to bring their wheelie bins in at night, and ensure they're not visible from the road.

"If residents are planning to go on holiday, police advise asking a neighbour or friend to bring them in rather than leaving them out over a period of days," McDaniel said.

Anyone who has any information that could assist police with their inquiries, or who witnesses any suspicious activity, is asked to contact Christchurch Police on (03) 363 7400.

Alternatively, information can also be reported to Crimestoppers on 0800 555 111.
