Pedestrians are being urged to be extra vigilant on the roads while the new two give-way rules are introduced as cars will move differently and some traffic signals may change.
"It's important to remember that these rule changes are not just about changing habits for drivers - it's all road users, including pedestrians, who must adjust," said NZ Transport Agency chief executive Geoff Dangerfield.
"Pedestrians should never pre-empt crossing signals; they should always wait for the green man, and now is more reason than ever to change these habits."
Mr Dangerfield also asked parents to ensure that they talk to their children about being a safe pedestrian and remind them that it is extra important to be careful when crossing the road.
Emergency services, buses, taxis and local authorities say they are bracing themselves for the upcoming give-way rule change with extra instruction for staff.
