The Government says the road toll remains far too high.
As at 20 June, 161 people had died on the roads since the start of the year, six more than at the same time a year ago.
Associate transport minister Simon Bridges says the number of fatalities is a reminder to the Government there is still more to be done to improve safety on the roads.
He says later this year, alcohol interlocks - devices that stop a car starting if the driver has been drinking - will be introduced as a sentence for repeat drink drivers.
A zero drink drive limit will also be a sentencing option.
Mr Bridges says the message for drivers is also clear; if they take chances on the road, they not only risk their life but also the lives of others.
