UPDATED 5.54pm: Parliament is set to pass into law tonight measures that will allow bars to be open for business during tournament games.

The Bill has passed its second reading in Parliament.

There are no restrictions on bars near schools opening during the tournament.

The Greens had lobbied hard for that restriction as a condition of them supporting the Bill.

Greens Co-leader James Shaw said they were prepared to support the Bill when it applied to All Black games only, a position both the Prime Minister and Justice Minister had advocated for.

"From what I understand their caucus has overturned what the Prime Minister and Amy Adams have suggested, which is that there would be a restriction on the number of games ... so actually it's the national party back benches that have overturned that recommendation."

Green Party health spokesperson Kevin Hague has argued that leaves us open to too much alcohol-related harm, such as "increased domestic violence, increased violence generally and all sorts of other harms, disturbance [between] two neighbours."

"I'm probably one of the people who'll be in the bar having a beer while I'm watching the games. That's never what it's been about for us. It's been about striking a balance."

At the Bill's first reading, Justice Minister Amy Adams said it was the Government's preference the measures be restricted to All Black games only, but she doesn't want to get ahead of what the final shape of the Bill will be.

"It wasn't a fixed position. We were simply saying there was an argument to having a look at whether that was appropriate. I'm sure they've weighed that all up and have given that some detailed consideration."

But the MP behind a push for looser liquor laws during the Rugby World Cup, ACT's David Seymour, is confident of support.

"I don't think the standard should be did the Greens get everything they want, but they certainly got a very fair hearing. For them to say that they were mislead I think is really quite spoil sport."

Mr Seymour said some of the concessions discussed earlier will be adopted.

"For example you have to have a good track record as an operator. I think the committee will probably land on that but ultimately I'm not a voting member of the committee. I've got to respect the committee stage and what will come out of that we will see very shortly."

The committee considering the Bill hasn't heard oral submissions on it - a significant departure from normal legislative process. But Mr Seymour said the two week time frame Parliament is operating under to pass the Bill into law was always going to impose constraints.

"We have had submissions. I've read a large number of them and I'd have to say on balance you've got a lot of support here. You've got whole city councils who are supportive, you've got the district licensing committees."

Labour Leader Andrew Little has said he will still vote for it.

"There are other communities in New Zealand, I think of South Africans, Tongans, Samoans, they'll want to watch their teams playing whether or not they're playing with All Blacks, so it was already an arbitrary distinction to draw."
