A trestle table is covered in piles of flyers, a cellotape holder weighing them down against the breeze.
There's an open packet of Cameo Cremes on the table, and behind it sits Brendon Warne: former gang member and meth cook; now an ordained minister, in a T-shirt with 'Anti P Ministry' stamped on the front.
This is the weekly 'walk-in' clinic of the Anti-P Ministry but at the moment it is more of a 'walk-by' clinic - no one is willing to give the group a space to meet.

Set up by Warne and his brother, the ministry is just one of the grassroots groups springing up across the country in an effort to combat the drug's effects on their own communities.
Mr Warne, who was working towards a level four drugs and addictions qualification, said the group had supported about 200 people in the last six months.
It met every week for those wanting support to quit, or to support those with friends or family with a methamphetamine addiction.
However, it was yet to find a meeting space and had been forced to set up shop on Dannevirke's main street in the meantime, with local store The Magical Journey providing an area for tea and coffee.
Group social worker Fiona Watson said it would be nice to have a proper space.
"I'm quite amazed because there's quite a lot of empty buildings
"We've approached a few people who say they can't do that - it's only two hours a week for goodness' sake."
Despite that, the group's presence in town was growing - its stickers could be found all over town and even on local police cars.
Mr Warne said he wanted to go into jails and help.
"They say I don't have all the paperwork, but I'm about to graduate, so be warned - here I come."
Senior Sergeant Jymahl Glassey said he knew Mr Warne through the Tararua Addictions Service and supported the social work he did.
"If there are people out there who are trying to use their initiative, to do something about it and if it's genuine, they need to know they have our support and we're in behind them trying to tackle the issue."
Addressing methamphetamine use and addiction needed to be a community effort, "instead of just leaving it for the police to do", he said.
