Dense fog disrupted travel across Auckland on Sunday, 29 March 2026, forcing dozens of domestic flight cancellations at Auckland Airport. An early airport update listed 22 cancelled services, but the number increased as low-visibility restrictions continued, with later reports putting the final total at approximately 48 cancelled flights.
The disruption was concentrated on domestic and regional routes. International flights continued to operate, although passengers with domestic connections still faced the risk of missed onward services, rebooking queues and longer waiting times.
Fog restrictions were eventually lifted after visibility improved later in the morning. Flights gradually resumed, but delays continued as airlines worked to reposition aircraft and crews affected by the earlier cancellations.
Flight cancellations increased throughout the morning
The first reported schedule update showed 11 departing domestic flights and 11 arriving domestic flights cancelled. Those figures represented the situation at that point in the morning rather than the final impact of the weather event.
Cancelled departures included services to Napier, Nelson, Christchurch, Wellington, Palmerston North, Taupo, Gisborne, New Plymouth and Queenstown. Another Queenstown departure was delayed while low-visibility procedures remained in place.
Incoming services from Christchurch, Wellington, Napier, Palmerston North, New Plymouth, Taupo and Gisborne were among the early cancellations. A Tauranga arrival was delayed and one Wellington service was diverted.
As the fog continued, additional flights were removed from the schedule. Later reporting indicated that approximately 48 domestic and short-haul services were cancelled before airport operations began returning to normal.
The changing total is important for travellers reviewing reports about the event. The figure of 22 reflected an early snapshot, while the higher figure covered cancellations recorded later as the disruption developed.

Fog restrictions lifted after visibility improved
Later in the morning, fog restrictions at Auckland Airport were lifted as visibility improved. Flight operations resumed progressively rather than returning to normal immediately.
Some passengers continued to experience delays because aircraft and crews were no longer positioned where airlines had originally scheduled them. An aircraft delayed on its first journey may be unable to operate several later flights on time, creating disruption long after the weather itself has cleared.
Passengers were advised to confirm their booking directly with their airline and check the airport’s official live Auckland Airport arrivals and departures before travelling to the terminal.
Ferry and road travel also affected
The fog was not limited to the airport. Reduced visibility was reported across Auckland’s motorways, harbour and coastal suburbs, turning the disruption into a wider city transport problem.
Ferry operator Fullers360 warned that six morning sailings between downtown Auckland and Waiheke Island could be delayed. The affected schedule included the 8am, 9am and 10am services in both directions.
Residents in areas including West Harbour reported hearing foghorns as vessels moved through the harbour in poor visibility. Traffic cameras also showed stretches of the city’s road network covered by low cloud.
Although drivers were not affected by airport-style cancellations, dense fog can reduce reaction time and make vehicles, lane markings and hazards harder to see. Motorists travelling through affected areas needed to slow down, increase following distance and avoid using high-beam headlights, which can reflect off fog and further reduce visibility.
Why fog causes airport cancellations
Modern aircraft may be equipped to approach and land in low visibility, but that does not mean an airport can maintain its normal operating capacity.
Aircraft must be spaced farther apart, ground movements may be slowed and pilots can require specific aircraft equipment and certification. Taxiing also becomes more difficult because crews must safely identify taxiways, signs, other aircraft and airport vehicles.
These restrictions reduce the number of aircraft that can take off, land or move around the airfield each hour. Airlines may cancel shorter domestic services to prevent delays from spreading across the rest of the day’s schedule.
MetService says Auckland Airport records an average of 19.3 foggy nights each year. Radiation fog commonly develops when the ground cools overnight under clear skies and light winds, causing moisture close to the surface to condense into tiny water droplets.
Fog often begins clearing after sunrise as the ground and surrounding air warm. However, even a disruption lasting only a few hours can affect flights for much of the day because domestic aircraft usually operate several closely timed sectors.
What affected passengers should do
Passengers should check both their airline booking and the airport departure board before leaving home. An airport may lift weather restrictions while individual flights remain delayed or cancelled because of earlier operational problems.
Travellers with connecting flights should contact their airline promptly if the first part of their journey is affected. Rebooking options, accommodation support and reimbursement rules can vary according to the airline, fare conditions and the cause of the disruption.
Weather-related interruptions are generally outside an airline’s direct control, so passengers should not assume every additional expense will automatically be reimbursed. Travel insurance may cover certain costs, but the policy wording and exclusions need to be checked carefully.
The Auckland event was caused by weather, but major flight disruption can develop for several reasons. Recent examples include Air New Zealand cancelling 1,100 flights during a fuel supply crisis and flight delays and cancellations affecting Manchester Airport.
Is the Auckland Airport fog disruption still continuing?
No. The fog restrictions linked to the 29 March 2026 event were lifted after conditions improved. The incident is no longer an active airport disruption, although it remains relevant for travellers searching for details about the cancellations and for understanding how fog affects Auckland’s domestic flight network.
The final impact was greater than the earliest airport update suggested. What began with 22 reported cancellations developed into a much broader disruption, with later reports indicating about 48 flights were cancelled before normal operations were progressively restored.
