As of June 2016,  both the Maui and Vector pipelines came under the ownership of First Gas Limited (First Gas). First Gas intends to replace the two existing access codes with a single transmission access code (GTAC). Gas Industry Co agreed to facilitate the new code development work with First Gas, each with its complementary responsibilities. Each has since consulted on and work-shopped  a range of papers addressing the various regulatory, contractual, design and process issues involved. 

In Gas Industry Co's 2006 Transmission Access Issues Review paper we identified access to short-term capacity on the Vector pipeline as an issue. In 2009, a capacity constraint on the Vector pipeline to Auckland and Northland caught some pipeline users by surprise and prompted further Gas Industry Co work as part of the Gas Transmission Investment Programme (GTIP).

While a few improvements have been made, some fundamental problems remain, and the objectives set out in our May 2010 paper: Options for Vector Transmission Capacity remain valid. These are to: ensure efficient pricing of capacity; ensure efficient allocation of capacity; promote efficient investment in capacity; facilitate competition in related markets; favour simple and transparent design and operation; allow price stability; provide the level of service firmness that users require and are willing to pay for; and minimise costs of transition from current arrangements.

The Current Arrangements section contains information on the Options for Vector Transmission Capacity paper that considers Vector's options for changing its commercial arrangements for transporting gas on its transmission pipelines and sets out the still valid capacity objectives.

The Developing section contains information regarding the work being undertaken by First Gas and Gas Industry Co to converge the two access arrangements into a single access regime. Here you will find all the consultations to do with this single code work which began in August 2016.

The Background section contains previous work relating to Transmission Access and Capacity including the Bridge Commitments and the original proposal for the GTIP work programme.
