Major changes to the social fabric of New Zealand are potentially on the horizon with the preliminary results today from the euthanasia and cannabis referendums.
The Electoral Commission is releasing the results at 2pm, but any close margin may mean another week of nervous waiting before the final results are unveiled on November 6.
The final tally will include 480,000-odd special votes, which at 17 per cent of the total count could be a decisive swing.
The euthanasia result, if recent polls are anything to go by, is expected to get across the line, meaning the End of Life Choice bill would become law.
The cannabis result is expected to be closer, with most recent polls showing the 'no' vote ahead, though some poll results bucked that trend in the weeks before polling day.
Special votes also tend to be more left-leaning, meaning a narrow lead for the "no" vote could be flipped on special votes.
Green MP Chloe Swarbrick said New Zealand was on the cusp of major social change that could improve thousands of people's lives, not only for those who suffer from an inequitably applied drug law, but also those who would benefit from more funding for health and addiction services.
"It is a pretty big deal. We haven't even begun to lift the lid on what this might mean in terms of the ability to help people."
"Theoretically it could be a bad poll, but it would have to be pretty wrong," Seymour told the Herald.
"I think that's a massive step forward for New Zealand as a humane and civilised society."
A large margin in today's result would effectively mark the end of the five-year journey for Seymour since he first put the bill into the ballot.
"A lot of people want to make a difference in their job, and a lot of MPs work very hard and - through no fault of their own - don't get the opportunity to make a major change in the law.
"So I feel very lucky in that sense. In practical terms it means that thousands in the next few years who might have had excruciating deaths will have control and dignity and choice."
Among those expected to be at Seymour's function are Shirley Seales and, via Skype from New York, Matt Vickers - the mother and widowed husband of euthanasia campaigner Lecretia Seales.
The referendum is binding and a majority "yes" vote would see it become law, with terminal patients able to request assisted dying from November 6 next year.
The cannabis referendum is not binding, but Labour has pledged to push the Cannabis Legalisation and Control Bill into law in the event of a "yes" vote.
A spokesman for the Drug Foundation said they were "slightly optimistic" given how special votes tended to be left-leaning.
A higher turnout this election (82.5 per cent turnout compared with 79.8 per cent in 2017) and Swarbrick's preliminary win in Auckland Central are also signs that more younger people voted this time, and they tend to be "yes" voters.
Swarbrick, one of the loudest voices in the "yes" campaign, will be at Albert Park fountain in Auckland at 3pm to address media.
An hour later, the Say Nope to Dope campaign will hold a press conference at the Urban Soul cafe in Manukau.
Campaign spokesman Aaron Ironside said a close result would not be surprising.
"We are aware that special votes may well be a swing to the 'yes' rather than the 'no'. We have a number in mind where we will feel confident that the swing votes are unlikely to undo that."
He wouldn't share the number, but said it was in the vicinity of the last 1 News Colmar Brunton poll, which had 51 per cent "no" and 41 per cent "yes".
The campaign would remain active if there was a majority "yes" vote, he said.
"We haven't worked out the 'how' but our intention is to participate in the [parliamentary] process to try and address the issues of most concern to us."
Those include minimising youth use, THC potency and proximity of licensed premises to vulnerable communities.
"We are of course still hopeful that it won't come to that. We are certainly aware that if [today's] result is very close, it would be unwise for either side to claim victory."
