Services on Auckland train lines are being disrupted due to "severe weather" on Wednesday evening.
Auckland Transport (AT) confirmed Western line and Onehunga line services had been impacted, and "delays and possible cancellations are expected on all train lines".
Onehunga trains between Penrose and Onehunga in both directions were cancelled around 4:45pm but as of 5:50pm were running the full route.
"Western Line services will continue to operate at a 20 minute frequency for the rest of evening peak. Southern & Eastern Line are experiencing 10-20 minute delays and possible cancellations," AT said.
Western line services had been impacted between Kingsland and Britomart, but as of 5:20pm, services were running the full route from Britomart to Swanson on a 20-minute frequency.
AT confirmed bus routes are also being affected by the weather.
"Due to the severe weather causing flooding and other incidents across Auckland, we are expecting very heavy traffic congestion network-wide.
"This will result in delays and cancellations to many bus and train services throughout this evenings' peak travel."
Car crashes are also causing delays on Auckland motorways.
A crash on the Southwestern Motorway blocked the right lane southbound just after the Maioro St off-ramp around 4:20pm.
Waka Kotahi NZ Transport Agency said the crash has now moved clear of lanes, but motorists still need to allow extra travel time.
On the Upper Harbour Motorway, a crash is blocking the left lane westbound just after Upper Harbour Bridge.
"Merge right with care to pass and expect delays," Waka Kotahi said.
The agency is urging Auckland drivers to "slow down, keep your lights on, increase your following distance and allow extra time during this evening's peak travel period" due to the wet weather.
A breakdown has also occurred on the Southern Motorway which blocked the right lane northbound after Redoubt Rd. The breakdown has now been cleared and delays are expected.
