High Load
Consent Request

Supported by

This website is supported by all South Island Lines companies and is intended to make it easier for you to apply for Over Dimension Consents, especially when the consent applies across Line company boundaries.

Transporting high loads can pose a risk when routes are not inspected properly.

Overhead lines clearance from the road surface may have changed overtime as a result of road resurfacing, vehicle coming in contact with the poles or soil disturbances caused by nature.

A High Load consent is required when transporting loads with an overall height of 4.8 meters and higher to secure electricity supply and ensure safety to the general public. Approval will be given based on the height and application time frames stated below:
