Maori Party co-leader Tariana Turia is disappointed National won't support a public holiday marking Matariki, the Maori new year.
Debate on a bill sponsored by Te Tai Tonga MP Rahui Katene was adjourned this week before it came to a vote, but National indicated it won't allow the bill to go on.
Labour was prepared to back the bill as far as the select committee stage.
Mrs Turia told Waatea News the concern seems to be around creating another holiday.
