"I know a lot of farmers find it very frustrating because the New Zealand high country is frequently held up as being a beacon of sustainable farming and international marketing of New Zealand," she said.
Listen to Jamie Mackay's interview with Kate Cocks on The Country below:
Since changes were mooted in the past 18 months, farmers have worked with Land Information New Zealand to get something in place that was workable, she said.
"The key is, I really think high-country farmers and the Government want the same thing: you want the land looked after and to be there in perpetuity for everyone to enjoy."
Many farmers get an unfair reputation for disrespecting the land and environment, she said.
"I think that's something that farmers are very focused on, is making sure we are farming sustainably."
"Essentially, this reality has come down to one minister's crusade to get farming out of the high country. Which is probably a bit blunt but that's how it feels."
High Country Accord Trust chairman Philip Todhunter said the Bill was poorly drafted and placed limitations on day-to-day farming activities.
"Under the Bill as it stands, we'd need to apply for consent to fence off a wetland or waterway and then another consent to put in a new stock water trough so our livestock can have a drink."
The proposed Bill was completely at odds with the Government's recent statements that "farmers, growers and producers will play a critical role in New Zealand's economic recovery", Todhunter said.
Sage denied the idea that she was out to get farming out of the high country.
"By ending tenure review the Bill will stop the privatisation process which has seen former Crown pastoral land once used for farming subdivided and sold for lifestyle blocks and similar development."
The Bill provides for improved management of over 160 remaining Crown-owned pastoral leases.
"I recognise and value the role high country farmers play in New Zealand's economy and the economic recovery ... this Bill is intended to help safeguard that reputation and encourage sustainable pastoral farming."
