David Seymour says a huge number of issues have been worked through in coalition negotiations and remains bullish a deal could be struck in coming days. 

The ACT Leader met with National's Christopher Luxon and New Zealand First's Winston Peters for their first three-way meeting at an Auckland hotel yesterday. 

Peters briefly returned last night, seemingly for further talks. 

Seymour told Mike Hosking that they've narrowed down what areas of disagreement remain but wouldn't be pressed on specifics. 

He says all three have promised not to disclose what issues remain, but you can see from the election campaigns what priorities each party has.
