Other ballot box locations will be advertised at a later date.
Chief electoral officer Warwick Lampp said voting documents should be ready by September 20 and if people are leaving town they can make a special vote at the council on that date.
"Legally, if people are away over the voting period they can have their voting papers sent to them overseas, or wherever they are, and as long as they are back before voting closes their vote will count.
"Otherwise they will miss out," he said.
However, Mr Lampp said 2016 could see the introduction of electronic voting which would solve those problems.
Even though it's too late to get on the electoral roll and have your voting documents posted out, it's not too late to get on the roll and make a special vote.
