It's election day in Tonga, with about 64,000 Tongans registered to vote.

They will be electing 17 People's Representatives for the 26 member legislature.

Tonga - a Pacific country of slightly more than 100,000 people - is a constitutional monarchy and this marks the fourth election since its political system underwent major reforms in 2010.

RNZ Pacific's correspondent in Tonga, Kalafi Moala spoke to Max Towle.
