Four people died during Queen's Birthday Weekend as the result of crashes involving cars driven by tourists.
On the first occasion, a campervan allegedly crossed the centre line and the impact killed Auckland woman Robyn Derrick.
The second devastating crash happened after a car driven by a tourist allegedly failed to stop at a stop sign. Three people in the car it hit died - Sally Summerfield, 49, her daughter Ella, 12, and Ella's's friend Abigail Hone, also 12.
Mrs Summerfield's husband Shane, 48, who was driving the car, is in a serious condition.
What absolute tragedies and our hearts go out to family and friends.
