The Hunter Thoroughbred Breeders' and Hunter Valley Wine and Tourism Associations have made the bipartisan call to the NSW Labor and Coalition parties ahead of Saturday's poll.

They want legislation passed within 100 days of the election prohibiting new open-cut, underground and coal seam    gas mining near wine and horse critical industry clusters.

Existing legislation in South Australia and Western Australia prohibits exploration and mining activities in the wine-making districts of the Barossa Valley, McLaren Vale and Margaret River.

Hunter Valley Wine and Tourism spokesperson, Stewart Ewen, said the time has come for both parties to deliver on their 2011 election promises.

"The equine and viticulture critical industry clusters are the bedrock of the Hunter’s agricultural and regional economy.

"Our industries have been mapped and recognised as nationally significant, yet they have not been protected from mining," Mr Ewen said.

The local thoroughbred industry claims Kentucky in the United States and Newmarket in the United Kingdom have laws in place to protect their equine industries from competing land developments.

Thoroughbred Breeders' President, Dr Cameron Collins, said together the Hunter wine and equine industries inject more than $4.5 billion to the NSW economy.

"[They] support nearly 100,000 jobs and attract over three million visitors every year to the Hunter region.

“Co-existence is a term used to avoid dealing with decades of bad planning [and] without appropriate buffers of at least 10km we cannot co-exist," Dr Collins added.

The Associations also want equine and viticulture within the proposed 10km limit in the Hunter Valley to be listed as State Significant agricultural lands under Schedule 2 of the State Environmental Planning Policy (Rural Lands) 2008.
