MotorSport says that young drivers often take part in these kinds of competitions.
The organization has said, though, that it will be doing a full investigation.
“The event took place on Arcadia Road in Paparoa which was closed to the public for the duration of the event under the authority of the local Road Controlling Authority,” a statement from MotorSport said.
“It is too early in the investigation to comment on what the main contributing factors to the crash were, however, it does not seem as though the road was in a detrimental or unsafe condition.”
“Our thoughts are with the families and friends of these two competitors and everyone involved with the Arcadia Road Rallysprint,” said Wayne Christie, president of Motorsport New Zealand.
“This terrible tragedy will, without a doubt, shock and upset everyone in the motorsports world.”
“We will be offering support to all those involved in the coming days.”
