Maori Party co-leader Pita Sharples says he likes the idea of a four-year Parliamentary term.
Dr Sharples and Deputy Prime Minister Bill English are co-chairing a constitutional review to consider issues such as the term of Parliament, the number of MPs, the future of the Maori seats and the place of the Treaty of Waitangi.
Prime Minister John Key has backed extending the term and Dr Sharples says he's finding it difficult to do a lot of legislative work in three years.
(In) the first year you're getting used to portfolios, the second year you work like hell and the third year is only a few months before the election campaign," he said.
Dr Sharples told Waatea News the workload has been made worse by Parliament sitting under urgency in the lead-up to the Christmas recess.
