"Overall voter turnout is slightly lower than in 2013," Lotu-Iiga said.
"The Government is open to looking at new initiatives to assist local government as it works to promote better turnout."
This included online voting, he said, but more work needed to be done to address concerns around security and vote integrity before a trial could take place.
"It is also important to note that international evidence suggests online voting has not led to a significant increased turnout in areas where it has been introduced."
Lotu-Iiga thanked those who did vote and congratulated those elected to seats.
"I look forward to building a good working relationship with mayors, councillors and board members elected today to deliver better value local services for ratepayers."
