"Limiting appeals is one of the key tools for fostering consensus and incentivising upfront engagement" Ms Adam told the Valuing Nature conference in Wellington today.
Ms Adams indicated appeals under the new collaborative approach would be limited to instances where there was "deviation from the collaboratively-reached decisions".
Current appeal rights would be retained where councils chose to continue with the Schedule 1 process.
Green Party environment and water spokesperson Eugenie Sage said the changes would reduce New Zealanders' right to appeal decisions that were detrimental to the environment.
"The Environment Court provides people who love our environment and our freshwater with a way to protect it. Limiting appeal rights and relying on buy-in by polluters will dilute protections of our freshwater, vital to our economy and way of life."
Meanwhile, Ms Adams also announced the RMA changes would clarify and enhance opportunities for iwi and Maori views to be explicitly considered before fresh water planning decisions were made whether councils chose the collaborative or Schedule 1 process.
Ms Adams said the RMA changes to be introduced later this year would not give iwi the right of veto over planning decisions.
