Auckland trains have been hit by faults during the morning rush with delays on the Eastern and Southern lines.
Auckland Transport says passengers can expect disruptions after an earlier overhead line issue and track fault.
Auckland motorways have also been hit by problems with a breakdown causing problems on the Harbour Bridge.
A vehicle had blocked the left lane heading north on the bridge just before 9am.
The New Zealand Transport Agency said it was quickly cleared.
It followed earlier problems on the Southern Motorway after a breakdown at Takanini.
