Abuse from members of the public directed to the group labelled the "unruly tourists" led to the eventual crash of their vehicle, a member of the family maintains.
Joe Doran told the Herald: "People were calling me gypsy scum and my father crashed the motor over people calling me gypsy scum."
Their green van was eventually abandoned by the group in Māngere and the abuse didn't end there, someone writing the word "Pikeys" on the back window.
Witnesses at the scene said the van went over the median barrier at the end of Thomas Rd and Massey Rd.
They said the British tourists caused quite a scene as they took all their belongings from the car and proceeded to walk along the road.
