"It could be fairly argued their decision, or decisions, would actually be better informed," Mr Caffell said.
He said the notes also say at the beginning of each triennium the mayor has the right to establish a committee structure that he or she believes would best support the council.
Existing committee structures could therefore change following the October 8 elections, and the new council would have to reappoint the iwi representatives -- if they chose to -- to policy and finance, or an alternative committee should the committee structure change.
"I think it is misleading too to say the May council decision was well consulted, particularly with the public.
"Sure there was a mention in the air but nowhere was there talk of appointments to policy and finance, voting rights and payments of $200 each a meeting.
"That only became known to councillors within 24 hours of the meeting and to the general public in the media the following day.
"If that's a good consultation process then I'd hate to see a bad one," Mr Caffell said.
At the May meeting a vote was taken to agree to the iwi appointments, which councillor Caffell and councillor Brent Goodwin opposed, mostly on the grounds there had been insufficient time given to sum up the situation.
The remaining councillors at the meeting being the mayor Lyn Patterson and councillors Mark Harris, Graham McClymont, David Holmes, Chris Peterson, Jonathan Hooker and Doug Bracewell voted in favour.
Iwi appointments would not extend to allowing voting rights at full council meetings, only at the Policy and Finance Committee and Audit and Risk committee meetings.
