Wairarapa bus company Transit took over the contract for half of Wellington city's bus routes in July. Since then there have been ongoing complaints of buses being late, too full to board or not showing up at all.

Auditor General John Ryan said following complaints to his office, his staff have met with senior personnel from the council and Transport Agency, as well as some of the bus operators.

But he was waiting for the outcome of Parliament's Transport and Infrastructure Select Committee on Thursday and other work that is already underway, before deciding if further inquiries are warranted.

The council was currently reviewing the system, which it expected to complete by the end of the year.

Meanwhile, Mr Ryan said his office would continue to monitor developments and review any new issues or information that come to light.

Last week, Greater Wellington Regional Council chief executive Greg Campbell said he took full responsibility for fixing the network's problems.

"Any commuter that is left stranded, or a bus that is late, that is of extreme concern," he said.

"We have to get a clear view of what is happening. What an independent review can really do - particularly for management and council - is give a view of what has happened and articulate that well."
