One commuter described chaotic scenes at Britomart, and said people were crying and shouting as they tried to work out how they could get home.

He added that replacement buses were not yet available, meaning some people could be stranded in the city for some time.

Southern, Eastern and Western line trains began running again about 7pm, with the loudspeaker announcement met with cheers from people on the station concourse.

Travellers were warned that the frequency of services would be reduced and they should expect delays.

Onehunga services remained suspended, and travellers on that route were advised to contact the help desk for booking on alternative routes.
