Aucklanders are being urged to cancel all unnecessary travel on Sunday as Cyclone Vaianu bears down on the region, with authorities warning of widespread and prolonged disruption across the transport network. Strong winds and heavy rain are forecast for Saturday and Sunday, prompting a multi-agency response to the impending severe weather.
The Auckland Transport Operations Centre (ATOC), a joint venture between Auckland Transport (AT) and NZ Transport Agency Waka Kotahi (NZTA), has activated its Incident Management Team to monitor the cyclone's impact. The centre is coordinating with MetService, Auckland Emergency Management (AEM), and emergency services to prepare the city’s infrastructure for the storm.
The most significant disruption is expected on the Auckland Harbour Bridge, a critical artery connecting the North Shore with the rest of the city. Officials have stated there is a high likelihood of extended closures on the bridge from midday until late evening on Sunday. Residents have been seen preparing for the storm's arrival, with many rushing to local supermarkets to stock up on supplies. You can read more about that here.
Bridge closure and road flooding expected
ATOC Incident Controller Zane Davidson said the current forecast puts the bridge at high risk of closure due to severe wind gusts. He advised motorists to consider using the State Highway 16 and 18 western ring route as an alternative, even ahead of any official closure.
Based on the current forecast, we expect there could be periods of extended closures of the Auckland Harbour Bridge between Midday Sunday until late evening. I would strongly advise checking the status of the bridge before you travel from now onward, as the wind trajectory can change quickly and we may see strong gusts from this evening.
Mr Davidson also warned of potential surface flooding from late Saturday evening, urging drivers to exercise extreme caution, particularly in low-lying coastal areas. He specifically highlighted the flood-prone section of State Highway 1 southbound after Esmonde Road on the North Shore.
The coordinated response involves extra resources to manage the expected impacts. “Our contractors have secured construction sites and loose debris where possible ahead of the Cyclone’s arrival,” Mr Davidson said. “They are on standby and to respond to increased flooding events and to keep a close watch on locations where slips may occur.” For the latest information on weather alerts, Aucklanders are encouraged to monitor the MetService website.
Public transport cancellations
Significant cancellations have already been announced for Auckland’s public transport network, primarily impacting ferry services. Pine Harbour ferry services ceased from 3pm on Saturday.
From 11pm Saturday until at least 9am Sunday, all Devonport, Waiheke, Half Moon Bay, and Hobsonville Point ferry services are cancelled. Rakino Island services are cancelled for the entire day on Sunday. All Waiheke bus services will also be suspended during this period.
Ferry operator Fullers360 is scheduled to conduct an operational review at 8am on Sunday to determine if and when Waiheke services can safely resume. Commuters are advised to check the AT Mobile app and the Fullers360 app for the most current information before attempting to travel.
The disruption comes as Auckland’s transport network undergoes significant long-term changes, including major investments outlined in the recently signed Auckland City Deal. Events like Cyclone Vaianu test the resilience of the existing infrastructure as the city works to build a more robust, multi-modal transport system for its growing population.
How to stay informed
Authorities are providing real-time updates through various channels. For the latest status of the Auckland Harbour Bridge and other state highways, drivers should consult the NZTA Journey Planner website.
Information on closures and flooding on local roads will be updated on the Auckland Transport website. Residents who encounter dangerous flooding on roads or footpaths are asked to phone Auckland Council on 09 301 10101. If the flooding is on a motorway, the public should call NZTA on 09 969 9800. Any situation posing an immediate risk to life should be reported by calling 111.
Mr Davidson emphasised that the joint operations centre is prepared for a sustained response. “ATOC monitors, responds, and communicates incidents and disruption on Auckland’s transport network 24/7, 365 days a year,” he said. The activation of a dedicated Incident Management Team ensures that additional, experienced personnel are on hand to manage the city-wide response throughout the cyclone event.
