Three driver were seen tailgating each other around Upper Hutt, with cars mounting footpaths and later colliding with two other vehicles, police say.
About 3.20pm yesterday, police received multiple calls from members of the public who witnessed drivers of a blue Nissan sedan, a grey Mazda Atenza, and a black Ford Mondeo sedan tailgating each other in and around central Upper Hutt.
"The drivers were seen to mount footpaths, narrowly missing pedestrians, and later colliding with two vehicles near McDonald's on Fergusson Drive," Sergeant Malcolm Lindsay said.
"The actions of these drivers are incomprehensible, and it's hard to believe nobody was injured as a result."
Police were following strong lines of inquiry and would like to thank the members of the public who have provided information.
Lindsay asked anyone who had dashcam or cell phone footage to contact police.
