New Zealand is contributing $US93,000 to support preparations for Tonga's November election.
Radio Tonga said the local government requested the funding from New Zealand.
The New Zealand High Commissioner to Tonga, Sarah Walsh, said the funding would go towards the printing of the electoral roll and ballot papers, public awareness, travel and training for election officials and the venue hire for polling stations.
The Supervisor of Elections, Pita Vuki, said they were finalising paperwork to be distributed to the outer islands next week.
Voting is due to take place on November 16.
