Members of the working party tasked with looking into different options for the Cathedral are being paid $800 a day.
The chairman of the working party, former NZ Transport Agency chief executive Geoff Dangerfield (right), is paid $1000 a day.
They are expected to meet about two days a month.
Other members of the working party are The Tannery developer Alasdair Cassels, business consultant Sue McKenzie and Anglican Church Property Trust board members Steve Wakefield and Roger Bridge.
They have been appointed to look thoroughly into "reinstatement options" for the Cathedral, and what different options will cost.
They will then put it together in a report to the Government and church, due by December 7 this year.
A Department of the Prime Minister and Cabinet spokesman said the fees were set with the Cabinet fees framework.
"[They] are set at an appropriate level to ensure the group has suitable expertise and experience, and to recognise the complexity of the task and strong public interest in the group's work."
