The election success of National has weakened the bargaining power of their support parties.
Prime Minister John Key yesterday said he had spoken to United Future leader Peter Dunne and Maori Party co-leader Te Ururoa Flavell. His office has spoken to Act MP David Seymour.
It was "highly likely" that National would have confidence and supply agreements with Act, United Future and the Maori Party and he expected to discuss ministerial positions with Mr Dunne and Mr Flavell.
