Bus journeys will be disrupted in Auckland on Thursday as workers meet with NZ Bus management to discuss a new pay deal.
NZ Bus runs all North Star, Go West, Metrolink, City Link, Outerlink and Waka Pacific routes across the region.
A three-year-old collective agreement expires on Saturday and the company says so far, pay talks have been constructive.
The Auckland Tramways Union is representing some drivers. President Gary Froggatt says the previous deal lasted three years so services during the 2011 Rugby World Cup would not be disrupted by pay talks.
Workers have been offered a deal of 2.3% from November this year, with a further 2.3% in November next year.
Mr Foggatt says his union is not endorsing the offer.
