Rule Changes

We take different perspectives into account so the rules we make are well considered and based on comprehensive evidence. 

Pending rule changes are rule change requests which we have received but not yet initiated under the rule making process. We endeavour to initiate rule change requests as soon as possible after receiving them, having regard to our work program.

When we initiate the rule making process for a rule change request, the request will be listed as an open rule change and we will invite stakeholders to provide submissions on the request. Generally, when we initiate a rule change request, we also publish a consultation paper to facilitate stakeholder consultation.

Once we have made a final rule determination on a rule change request, the request will be listed as a completed rule change.
