The council is not required to consult the public before making a decision - but it seems likely no conclusion will be made on the issue without consultation.
Dunedin electors decided in a close poll in 2003 to change to STV.
Dunedin is one of few local authorities to use the system.
The council finance and strategy committee will consider a report by electoral officer Pam Jordan, which recommends it either confirm STV or return to FPP.
[comment caption=Do you think the DCC should change the voting system?] Committee chairman Cr Richard Walls yesterday confirmed that under the Local Electoral Act the council could make a decision to return to FPP without public input.
However, his intention was to suggest the committee make either a tentative decision, or no decision at all, to allow a period for public submissions.
Asked what he thought the feeling of the council was on the matter, he said there had been no formal or informal discussions.
"It's up to the council to talk about it tomorrow."
Ms Jordan's report said the council was required by the Act to make a decision by September 12 if it wanted to change the system before the 2010 elections.
The district council and district health boards use STV, which requires voters to rank candidates with a number, while the Otago Regional Council uses FPP, which requires a tick beside one candidate's's name.
The use of two systems has been criticised as confusing for voters.
The report said the council was not required by law to make a decision - the present system would continue if it did not.
The other ways the system could be changed were by a poll demanded by electors, as occurred in 2003, or a poll held at the initiative of the council.
Cr Walls said the STV system Dunedin had was too complicated.
He also said the matter should not have come up before a review of the ward system, another aspect of the electoral system subject to criticism, which would happen next year - something he blamed on legislation agreed to by Labour and the Green Party.
Whatever decision the council made, proponents of either STV or FPP could organise another poll, as long as they got the backing of 5% of electors.
The cost of such a poll was estimated at $125,000.
