Auckland Transport refuses to say if it will keep giving passengers with only old purple Snapper Hop cards free trips on buses equipped with newer technology.
That is despite a revelation by a bus drivers' union leader that NZ Bus has told staff not to turn away passengers with the wrong card for now.
The council transport organisation allowed passengers without its new dark blue AT Hop cards free rides yesterday, after almost half of the 294-strong Metrolink bus fleet switched to its $100 million electronic ticketing system at the weekend.
Spokeswoman Sharon Hunter said the grace period was for a minority of passengers who might have missed extensive advertising of a need to carry both cards - or cash - while all NZ Bus subsidiary fleets are changed to the AT Hop system between now and the end of the year.
Asked how long the freebies would continue, she said: "I can't say, but it is very brief - that's about to disappear, so get with the programme."
