The Cook Islands chief statistician Taggy Tangimetua says preparations for next week's by-election for the tied Akaoa constituency on the main island Rarotonga are almost complete.
Ms Tangimetua says the main and supplementary rolls have closed while the postal votes will stay open till at least Monday for the southern island groups, with advance voting continuing until election day.
She says however, there's been a small increase in in voter numbers from the September general election for the by-election on November the 28th.
"The electoral role in comparison to the last general election. It's slightly higher, but not that many, less than 20 extra persons that have registered."
