New Labour Party transport policies, which include plans to ban trucks from around 8 per cent of New Zealand's motorway network, have been met with a mix of praise and scepticism.
Truck drivers said preventing them from using the outside lane on three- and four-lane highways would be unworkable and unlikely to reduce congestion.
The Automobile Association (AA) also questioned the policy, saying its members had never cited trucks as a cause of congestion.
But the AA strongly backed other Labour measures such as scrapping registration fees of $35 for light trailers and caravans and reducing charges for motorhome owners.
Labour leader David Cunliffe said "Kiwis are sweating the small stuff too much" and Labour's changes would reduce frustrations during public holiday periods.
