Agency manager Rick Barber said levels were similar to previous years. He encouraged unhappy customers to complain to taxi companies. If that did not resolve the problem, they should contact the agency.
Nine months after three different taxis left her and two friends stranded on a city street late at night, Amy Keene still can't believe how they were treated.
Three drivers refused to pick up the Hamilton early childhood teacher and her friends from Vector Arena in central Auckland in September last year because their Parnell hotel was too close to be worth the fare.
After being forced to walk, Keene complained to the taxi companies but was told nothing could be done because she didn't get identification numbers.
"It was terrible what happened to us. It should really not happen to anyone."
New Zealand Taxi Federation executive director Tim Reddish said the number of complaints was low considering the number of taxi journeys each year.
"There's 8000 taxis on the road and they make millions of journeys each year.
"Auckland Co-Op makes six million journeys a year alone most taxi rides take place without incident every day."
Sometimes complainants were in the right, but they could be mistaken too, particularly when affected by alcohol.
"We're always trying to improve service, and one complaint is too many, but I don't think we've got a big problem."
