All six people had moderate injuries, the spokesperson said.
"Three were transported to Dunedin hospital; the remaining three were treated at the scene."
An eyewitness said emergency services vehicles were still at the scene on Portobello Rd at Vauxhall at about 10.45am, although the rescue effort appeared to be over by then.
