A Merivale jewellery shop has been targeted by robbers in a daylight smash and grab.

Petersens Jewellers was hit just before lunchtime on Monday on Papanui Rd.

The Herald understands three people dressed in black entered the shop about 11.45am and robbed the jewellery store.

The shop is near a childcare centre and a school. The daycare was open at the time, but the school was closed for the school holidays.

Two police officers are at the shop making inquiries into what happened.
