A truck has ploughed into a Porsche dealership, injuring two people and damaging several luxury cars in the Auckland suburb of Newmarket. Emergency services were called to the crash involving at least six vehicles at the Porche showroom on Great South Road at about 11:30am. Inspector Lou Alofa said the driver of a truck and trailer unit had lost control and hit five parked cars outside the showroom. St John's ambulance spokesman James Ihimaera said one person was taken to hospital with seriously injuries. Another person with moderate injuries had to be freed from their vehicle by the Fire Service, Mr Ihimaera said.
