Tourism operator Explore Group is quitting its ferry service to Waiheke Island just a year after it started.
The company is blaming dwindling passenger numbers and its exit raises the prospect of increased fares.
Explore Group managing director William Goodfellow said the decision to stop the service was difficult to make, especially because of the support the company had received from passengers and the investment it had made over the past two years.
"We've thrown everything we could at the Waiheke service and we greatly appreciate the support of Waiheke and Auckland travellers, however, the initial strong support from commuters was not sustained and ultimately the numbers did not stack up."
The service would run its regular schedule until May 8. There were a number of contributing factors, including infrastructure problems that prevented the company from offering passengers a comfortable experience, especially during the winter months, Mr Goodfellow said.
