The first rollout in South Auckland last October reversed a decline in bus patronage, and led to a 15 per cent increase in passenger trips and 2 per cent growth in overall journeys.
The rollouts of new bus networks in South and West Auckland will be followed by east Auckland in December, central Auckland in the first quarter of next year and north Auckland in the second half of next year.
Main rejected the criticism about the new West Auckland services, saying Auckland Transport received 1200 submissions on the proposed changes and had made changes to 11 of the 24 routes.
The reason the Westgate-to-city express service does not run exclusively on the motorway, Main said, was about providing a good catchment of commuters and using bus priority off the motorway for the quickest possible journey into the city.
The express buses were able to travel faster at times off the motorway than when the motorway was congested, he said.
Main said the premise of the new network was for higher-frequency buses, which would lead to a "hub and spoke" model for commuters to transfer to major interchanges at Westgate, Henderson and New Lynn.
"Feeding people into major interchanges and providing frequent services is a fundamental part of the implementation of the new network. It may require people to change buses but will also provide a higher frequency and quicker trip times," Main said.
He said brochures about the new West Auckland network had been mailed to 97,000 households and there were videos on social media, ambassadors and staff out on the network over this week and next week, and 400 bus drivers up to speed and able to answer questions.
