Farm vehicles that operate below 40km/h won't need warrants of fitness under rule changes announced by the Government.
Other changes include allowing farmers who hold car licences to drive a wider range of agricultural vehicles and making all vehicles use flashing beacons when they're on the road.
The rule changes will come into force during the first half of next year.
Associate Transport Minister Simon Bridges says they're the result of a review that began in September last year.
"The sector was concerned the laws don't take into account the special nature of agricultural vehicles or the demands of agricultural production," he said on Wednesday.
There are 40,000 registered farm vehicles in New Zealand.
