Motorists were pelted with rocks and a wooden pallet from an overbridge in an early-morning attack on a new expressway north of Wellington.
Kāpiti Coast police were calling for community help after the attack on multiple vehicles on the $630 million new Kāpiti expressway.
Police said at about 2.30am on Thursday an “unknown person or persons” threw objects including rocks and a wooden pallet from the Ngārara Rd over bridge at vehicles travelling below along the expressway.
They said a number of vehicles were damaged – including five trucks and a car – in an attack which “could have easily caused serious injury or death to any of the motorists”.
The Ngārara Rd overbridge is in a largely rural area in the north of the about-18 kilometre expressway. It runs from Waikanae township and connects to the nearby Nga Manu Nature Reserve.
The expressway includes multiple over bridges along its length, including the Ngārara Rd bridge, and bridges at Paraparaumu and near Poplar Ave in the south.
