Auckland Transport has cut fares for a ferry service to the upper harbour only three weeks after launching the service.
However, a much criticised disparity in fare prices between two communities served by the ferry remains.
Auckland Transport is reducing fares by 15 - 30% on the ferry to Hobsonville Point and nearby Beach Haven as a three-month special offer.
Hobsonville commuters will continue to pay higher fares for a similar distance on the same ferry.
The Prime Minister John Key is the Helensville MP, an electorate that covers the Hobsonville community, and said at the launch that the community there had grounds to feel hard done by.
Auckland Transport said the special deal was to boost numbers. Patronage has averaged between 15 and 20 passengers on peak-hour weekday sailings.
