At New Zealand First's convention in South Auckland on 16 July 2017, Peters announced that if elected his party would hold a double referendum on eliminating the Māori seats and reducing the number of MPs in Parliament from 120 to 100 in mid-term 2017–2020. Peters also outlined his party's policies which included reducing immigration to 10,000 a year and nationalising the country's banks. Peters also proposed making KiwiBank the New Zealand government's official trading bank. In terms of law and order, Peters said that his party would build no more prisons but would make prisoners do hard labour six days a week.
