Two males are in custody after threatening a driver with a gun, stealing his car and using it to ram a police vehicle, police say.
They were both injured in the alleged crime spree.
One of the alleged offenders pointed a firearm at a man in a car in Cornwall Park, Hastings and told him to get out of the vehicle about 6.20pm, Senior Sergeant David Sutherland said.
The alleged car jacker then drove in the victim's car along Tomoana Rd towards Heretaunga.
Police spotted the car in Mayfair and followed it to Camberley before it sped off about 9pm.
