More meetings between Prime Minister John Key and minor party MPs are expected on Thursday, as National moves to set up a new government.
Mr Key met with the leaders of ACT, United Future and the Maori Party on Monday to begin bashing out supply and confidence deals.
He's hopeful of wrapping up agreements with ACT and United Future within days, while the Maori Party hold hui, or meetings, with its members before deciding whether to continue supporting the National-led government.
Mr Key is expected to meet with ACT MP John Banks and United Future leader Peter Dunne in Wellington on Thursday afternoon.
The ACT Party board met on Wednesday night, for further discussions on what it wanted from a supply and confidence deal with National.
Mr Banks told NZ Newswire the agreement would have to build on the deal the party reached in 2008.
That included establishing the 2025 Taskforce to investigate closing the gap with Australia, National's support for ACT's three-strikes legislation, and two ministerial portfolios.
"Eighty percent of what we've already discussed, we can tick off quickly," Mr Banks said.
"But there'll be 20 percent at the margins that is important to the ACT Party, because we are underpinned by certain values that we want represented in any such agreement."
Each party is expected to be offered ministerial portfolios.
Mr Dunne is likely to continue as revenue minister, while Mr Banks could receive a business-related role.
Maori Party co-leader Pita Sharples is expected to retain the Maori affairs portfolio.
