Wellington bus drivers have voted to strike indefinitely.

Drivers will walk off the job on October 23, and stay on the picket line until the Tramways Union and bus operators can settle a collective agreement.

Union Secretary Kevin O'Sullivan says it's been a long time since Wellington drivers have thought about industrial action.

"1996 was the last time we did anything, and even that wasn't on this scale."

O'Sullivan says there's no date set for a meeting between operators and the union - and he has no idea when he'll hear from them.

"I'm expecting we will. I hope we will! It would be pretty silly to not touch base with us, but who knows."

It is the latest blow for the troubled network.

The capital's transport network has been under fire since new routes and timetables were launched earlier this year, leading to widespread delays and cancellations. 

Greater Wellington Regional Council's CEO Greg Campbell has cleared his timetable to focus exclusively on the network.
