The front of the Rotorua Aquatic Centre has been badly damaged.
A police spokeswoman said police were called to the scene about 5.45am and it appeared the building had been hit by a car some time overnight.
She said the car was not at the scene and inquiries were being made in relation to any potential CCTV footage that might be available.
A worker at the centre said they had no idea what had happened or when exactly, but suspected it may have been caused by a car hitting the doors in the early hours of this morning.
She said they reported it to police and officers had been down to the scene to investigate.
