Locals took up this fight at the start of the year and it's been a huge weight on their shoulders for months.
Among their concerns were odour, pollution, flooding risks, not to mention the build being on sensitive land close to a marae.
Many said they'd be unsuccessful in their protest ... that it'd be impossible to stand in the way of big business and win.
But they have. No Tegel chicken farm for Northland, the Overseas Investment Office has scrapped it.
Tegel's obviously disappointed, it cites all the jobs it would've created in a region no one can argue doesn't need jobs.
But locals argued the 30-odd jobs on offer didn't outweigh the health risks to their people.
A spokesperson said the stench from the place would have compromised air quality and the pollution would've negatively impacted people's lung capacity.
Locals argued it'd be better to boost smaller scale farmers, instead of backing foreign owned companies like Tegel.
But Kaipara locals are at odds with their own mayor ... who says that jobs on the farm would've provided valuable employment, and that saying no to Tegel sends a signal that Northland is closed for business.
He's concerned the government is actively discouraging investment in the district. He's worried about the 6 per cent unemployment rate. Those are all valid concerns.
So whose right and whose wrong?
Well the tricky thing here is always the fine print.
While Tegel was touting jobs for locals and environmental care, there's no guarantee this would've materialised.
It's possible the amount of upset locally, would've proved too problematic to make it viable anyway.
What this whole experience does exemplify is the power of the people, the power of protest.
The locals took this fight seriously and opposed it with vehemence, and this week that translated into a win for them.
