Wellington Police are seeking the public's help to map the movements of two cars that were at the centre of an incident yesterday which began on State Highway 1 near the Basin Reserve.
Acting detective senior sergeant Steve Wescott said they understand the vehicles were a red-coloured Mazda sedan and a green-coloured Subaru Legacy station wagon.
He said they travelled together through the Terrace Tunnel and came to a stop on the Tinakori Road off-ramp just after noon.
At about this time, Police said they received reports that the Subaru Legacy was on fire and two people were arrested at the time.
