The push by One Nation's Mark Latham to overhaul lawmaking in NSW will be investigated by a parliamentary committee.

The NSW leader of Pauline Hanson's party moved a motion in the NSW upper house last month to change the way contentious laws such as council mergers or the greyhound ban are considered.

A key aspect of the proposal was a requirement for community input into controversial laws through a citizens' panel or jury.

Greens' MLC David Shoebridge amended Mr Latham's motion and the proposal will now be considered by the upper house's procedure committee.
