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), and is updating associated business practices, systems, and documentation. The GTAC is expected to come into operation on 1 April 2020. Information about the development of the GTAC can be found here.
While a GTAC post-implementation review is possible, Gas Industry Co has no further work in relation to security and reliability in prospect.
