Mr Pederson and Mr Roberts were both thrown form their bikes and died from impact injuries. Mr Roberts' partner, a pillion passenger, was thrown about 23m but survived. Mr McElrea said police should be given power to allow the prohibition of driving on the basis of demonstrable lack of ability.
Mr McElrea also said the Minister of Transport, Simon Bridges, should consider preventing overseas visitors to New Zealand with inadequate experience being deemed to hold a full New Zealand driver's licence on the basis of a driver's licence obtained overseas.
Mr Pederson's partner Lisa Milgrew said foreign drivers should undergo some sort of testing before they were allowed to drive in New Zealand.
"Something needs to be done, that girl had her licence for five minutes so they need to change something.
"In the beginning I just thought accidents happen, but when I found out people had rung up about her driving ... She should not have been driving at all. She ... comes here and drives on the open roads ... She left here the next day and a $10,000 fine for three people," she said.
