Doug Martin of MartinJenkins, who is leading the inquiry, will be able to make comment on any broader systemic matters considered relevant to the review.
Martin will have access to and support from Wellington Water's chief executive and staff.
He will be provided with all relevant documentation, and interviews with relevant staff, and stakeholders when requested.
Martin has been authorised to request and obtain any further documentation from management as considered necessary.
Wellington Water chairwoman Lynda Carroll said this afternoon there was no doubt in her mind that staff would fully co-operate with the inquiry.
"Expectations have been set very clearly with staff and management about the importance of getting this right for the Wellington public."
Carroll said the board also wished to apologise to Wellingtonians who rightfully had an expectation their water would be fluoridated.
"We also wish to acknowledge the concern this situation has caused.
"We understand the public's desire for more information and answers as to how this situation occurred. The Board share that desire, which is why we have commissioned the independent inquiry – a vital step to achieving this clarity."
In the meantime, Wellington Water is working "at pace" to restore fluoride at the Te Maura and Gear Island water treatment plants, Carroll said.
"I want to assure the public that we are working as quickly as possible to safely restore fluoride into the water for Upper Hutt, Porirua, Wellington City, Stokes Valley and Manor Park."
The Wellington Water operation team will be providing regular updates without predetermining or compromising the integrity of the inquiry, she said.
The inquiry's final report is due by May 31, 2022, and the findings will be made public.
