Thieves used a car to pull off the doors of Peaches & Cream, on Colombo St in Christchurch, early on Monday morning, before taking off with cash registers.

Burglars have pulled off an early-morning heist on a central Christchurch adult store.

A group of people used a car to yank off the doors of Peaches & Cream on Colombo St about 3.30am on Monday, a police spokesman said.

"They targeted the cash registers, so we don't know exactly how much they've gotten away with," he said.

Officers would work at the scene throughout the day, he said, taking fingerprints and reviewing security and traffic camera footage from the area.

"We are also asking the public, if they know anything or have seen anything, to get in touch."

It was the city's second burglary in 24 hours where a vehicle was used to gain entrance to a store.

On Sunday, power tools and stock were stolen from Jemmett's Power Tool Service in Hornby after a car rammed through the shop's doors.

The Shands Rd store was broken into about 6.50am and was extensively damaged in the ram raid.
