The Representation Commission

The Representation Commission is the independent body that carries out the boundary review.

The next boundary review is scheduled to take place in 2019/2020 to fix new boundaries for the 2020 and 2023 General Elections. 

The first step in the process is for the Government Statistician to provide electoral population information to the Surveyor-General.  The Surveyor General then draws up the provisional boundaries which are used as the starting point for the Representation Commission’s deliberations. 

The review must be completed within six months of the Representation Commission starting their deliberations on the proposed boundaries.
