Suppliers of gas pipeline services are subject to the regulatory provisions under subpart 10 of Part 4 of the Commerce Act 1986 (the Act). Subpart 10 provides that suppliers of gas pipeline services are subject to default/customised price-quality regulation and information disclosure. Gas pipeline services include both gas distribution and transmission. Because of the differences between gas distribution and transmission services, the Commission has made separate input methodologies determinations for each service.
The Commission made its input methodologies determinations for gas pipeline services on 22 December 2010 and published the determinations in the New Zealand Gazette on 20 January 2011. The input methodologies determinations for gas pipeline services include input methodologies that apply to default/customised price-quality regulation and input methodologies that apply to information disclosure regulation.
The determinations includes input methodologies for asset valuation, cost allocation, regulatory tax treatment, the cost of capital, pricing methodologies, regulatory rules and process, and matters relating to customised price-quality path proposals.
The Commission must review each input methodology no later than 7 years after its date of publication and, after that, at intervals of no more than 7 years.
On this page you will find the gas pipeline services input methodologies determinations and the associated Reasons Paper located in Supporting Documents under heading Input Methodologies for Gas Pipeline Services. Documents relating to consultation undertaken by the Commission in making the gas pipeline services input methodologies determination can be located on the input methodologies consultation page.
On 8 March 2011 the Commission published a memorandum on its process for considering requests for amendments or clarifications of the Part 4 determinations it made in December 2010. This process document along with a summary of requests for amendments or clarifications and the Commission's responses can be found below under Requests for amendments or clarifications.
