Environmental groups say a proposed rewrite of the Resource Management Act pushes economic growth at the expense of the environment.
Six groups are calling for the rejection of recommendations made to the Government by an advisory group.
The advisory group's report recommends changing parts of the act by replacing words such as "preservation" and "protection" with phrases such as "recognising and providing for" in areas of environmental concern.
Opponents including the Environmental Defence Society say that is an attack on legislation designed to protect the natural landscape.
They say if the recommendations are implemented, it would weaken the act and lower the standards for gaining resource consent for development.
However, Federated Farmers says changes are needed to achieve a better balance between environmental protection and growing the slow-moving economy.
