Christchurch police are warning home owners to tighten up on security - after arresting 11 people for burglaries.

A number of items were taken from properties over the past two weeks..

Police say the arrests resulted in the recovery of a $15,000 Yamaha power boat motor, three vehicles, firearms, cash and methamphetamine.

Area Prevention Manager, Acting Inspector Paul Reeves says burglars are looking for an easy target during the summer months - so homeowners should ensure they lock houses and cars and keep valuables out of sight.

He's urging neighbours to report anything suspicious and if there's a vehicle involved to record the number plate.
