Commuters left fuming after buses on Auckland's North Shore cancelled without notice following strike

Bus services on Auckland's North Shore have resumed after they were cancelled without warning following a strike this morning.

Commuters took to social media to complain that Auckland Transport (AT) had not updated its app to alert people as soon as they were made aware of the strikes.

"You have an app why on earth did you not think to put a notice on it!" one Facebook user wrote on AT's Facebook page.

One Facebook user commented on AT's Facebook page that commuters should not have to find out about the cancellations on social media.

"Update the app.. Update the boards.. Don't expect ppl to find it via social media," another Facebook user said.

In a tweet, AT wrote, "Due to a bus depot on strike without notice, some NZ bus services are not operating this morning".

"This strike without notice may affect the following services: 82, 101, 105, 110, 129, 801, 802, 805, 806, 807, 814, 842, 843, 923 & 924. We will have more updates shortly. Thank you for your patience and understanding."

School bus services were covered, the transport agency said.

The strike did not affect Northern Express services.
