A block of houses under construction in Pegasus Town have been targeted by thieves, who made off with copper piping and heat pump units.
Police said it is the latest in a spate of thefts at building sites across Canterbury, with reported thefts increasing as construction activity around the region gathers pace.
Sergeant Graeme Crosson said thieves made off with copper piping and heat pump units from 13 houses on Infinity Drive.
Short lengths of copper pipe used for heat pump installations were stripped off the exterior of all of the houses in the block.
Heat pump condensor (outdoor) units valued at around $2000 each were taken from three houses.
The thieves also gained entry to one of the units through a garage door and stripped an amount of copper piping from inside the house.
Sergeant Crosson says the amount of copper piping taken was not of particularly high value, but the thieves caused considerable damage to the exterior of some of the homes.
The thefts occurred some time during the weekend.
Police are appealing for anyone with information about the thefts to contact them.
"The offenders would have required a large vehicle or vehicles to transport the stolen items, and they may have looked like genuine tradespeople," he said.
Detective Senior Sergeant Corrie Parnell said subdivisions in the Selwyn district and Wigram have also been targeted in recent months, along with individual building sites.
"In many cases these will be opportunistic crimes, but there's also the possibility of well-organised thieves deliberately targeting construction projects."
Items taken include household fittings and appliances, metal, tools and vehicles.
He urged builders, project managers and contractors to make their sites secure, using fencing, locks and hiding valuables away.
"Vehicles and heavy equipment may also be targeted. At a minimum, make sure keys are removed and vehicles locked."
Anyone with information about the thefts at Pegasus is asked to contact Rangiora police on (03) 313 6167.
