The Accident Compensation Corporation is to launch a programme to cut the high number of accidents involving occupational vehicles.
ACC believes about 30 deaths a year occur in such accidents, accounting for about a third of all workplace deaths.
The programme's manager, Sandra Nelson, says claims relating to work vehicle crashes could cost ACC nearly $30 million this year.
She says companies whose employees do high mileage will be asked to re-examine their road safety policies and procedures, paying attention to speed, restraints, drug and alcohol issues and the scheduling of journeys.
Ms Nelson says 64% of companies involved in a pilot programme felt it was sufficiently worthwhile to be introduced nationwide.
