MPs will tonight - and likely tomorrow - rush through a bill to legally create a public holiday next Monday to mark Queen Elizabeth II's death.
The Government had already announced Monday, September 26, to be a national holiday to commemorate the monarch's passing.
But as Parliament adjourned last week to mourn her and Prime Minister Jacinda Ardern travelled to England for the funeral MPs were unable to create the law required.
With the House sitting again this week, later tonight MPs will debate and vote on the Queen Elizabeth II Memorial Day Bill.
The day is to include a national memorial service in Wellington, beginning with a national minute of silence starting at 2pm.
