Speed limits of 110km/h could be on the way.
Associate Transport Minister Craig Foss has revealed the Government is still considering increasing the speed limit on certain roads.
"There are potentially some roads - very high-class, Roads of National Significance - where that is possible," Mr Foss said today.
"We are doing a bit of work in that space at the moment, no final decisions yet.
"Potentially the Transmission Gully, maybe the new Tauranga Motorway, the new road north of Auckland, the Waikato Expressway - that kind of class of road is potentially able to cope with [an increased speed limit]."
