Users of some Auckland bus services face disruption from next Monday when a new law on paid work rest breaks comes into effect.
Auckland Transport, which subsidises many bus services, said around 120 of the 13,043 services operated daily will be cancelled or altered - "less than one per cent".
Most of the affected services would be off-peak.
"Auckland Transport has worked closely with bus operators and unions to minimise changes to services, brought about by an amendment to the Employment Relations Act."
"The changes come into effect from Monday ... and prescribe more regular work time breaks for bus drivers. This in turns means some timetable changes, or service cancellations."
