A TV3 poll out tonight shows 57 percent of respondents believe Parliament should have raised the drinking age to 20.
40 percent favour keeping it at 18.
Prime Minister John Key says it reinforces the way he voted.
"I'm not surprise the public think that. I mean what it shows you is there's a divided views but that was one of the reasons why I voted for it to go to 20, I think that's in line with what the public thought and parliament didn't vote that way."
