A bus has broken down in the Auckland International Airport drop-off zone during one of the airport's busiest days of the year.
The airport tweeted that the zone was temporarily closed and traffic wardens were diverting traffic into the carpark. There would be free 10-minute parking.
The airport said yesterday that today was one of the busiest of the summer and asked passengers to allow an extra 30 minutes for their journeys through the terminal.
Two weeks ago, passengers missed flights and up to a dozen Air New Zealand services were delayed after crew were caught in gridlock around Auckland Airport.
Air New Zealand is rostering more staff on to help passengers through terminals over Christmas and is communicating with those it can reach to advise them to expect congestion.
Thousands of people have reported issues accessing their accounts.
