A proposed Templeton Quarry would cost a racing stables their life-long business.
Construction giant Fulton Hogan has plans to build a 170 hectare quarry on Dawsons Road in the Selwyn District. More than 25 horse owners, breeders and trainers would be directly affected.
Racing stable owner Sandi Curtin says their training track runs right along the road and there's no way owners could leave their horses to be trained if they can't guarantee their safety.
She says with 500 trucks a day down the road, it would just be a matter of when - not if - there was an accident that killed or injured a horse or trainer.
Curtin says Fulton Hogan agree it would be the end of their business if the quarry goes ahead.
They are worried that, with safety and dust issues, their property wouldn't be worth anything and no one will want to train there or buy it.
"Incredibly stressful. Just constantly it's something you think of from the minute you wake up till when you try and sleep at night. My husband and his family, 55 years they've trained here and at our age where do you go from here? How do you start a new business."
Curtain says they have staff and families relying on them for their income too.
