The Government looks like its stepping back on a three waters provision that would make it harder for future governments to change the legislation
The Green Party wants any move to privatise water to require sixty percent of MPs support.
The provision is unusual because new governments usually have the option of overturning legislation with a simple majority of parliamentary votes rather than trying to muster a super-majority in the House.
National says it intends to repeal any three waters legislation.
University of Otago law professor Andrew Geddis says such a provision is a potentially "momentous" change to how the country's law is made.
He spoke to Guyon Espiner.
