National's Nicola Willis is defending Luxon as he extends post-election coalition talks.

Luxon has begun another week of discussions with coalition partners ACT and NZ First, and it's looking less likely he'll attend APEC on Wednesday.

The Finance Minister-elect says she's not going to go into detail about who's talking to who, but coalition discussions are progressing. 

"We're making sure we're getting through the issues that matter so we can sign agreements, go to the Governor-General and form a Government."
