Police say they'll continue to target unsafe driving after seven deaths on the roads over the official summer holiday period

Director of Road Policing, Superintendent Steve Greally says people need to make sure they are always driving free from alcohol, drugs and fatigue.

He says everyone in the vehicle needs to be safely buckled up, and people should put their cellphone away at all times.

Greally's told RNZ, people also need to drive under the speed limit, at a safe speed for the conditions.

He says Police have tripled their efforts against speeding and alcohol testing, and many people haven't been getting the message around speed.
