Buses will be disrupted in Wellington today as drivers stop work to vote on a new pay offer from NZ Bus.
It's the latest development in a long-running saga over their collective agreement, which has already resulted in stop-work meetings, a strike and a lockout.
The last collective agreement was the third offer to be rejected by Tramways Union members, but the first to have the union's backing.
When the most recent pay offer was announced, Greater Wellington Regional Council chair Daran Ponter said it was a positive step forward.
"It is a credit to both the Tramways Union and NZ Bus that they've remained at the table to continue negotiations on their collective agreement."
