Tēnā koe Michael
Thank you for your email of 18 April 2026, to the Ministry of Business, Innovation and Employment (MBIE)
requesting, under the Official Information Act 1982 (the Act), the following information:
I seek recorded information relating to fuel composition, additives, approvals, monitoring, and
cost components in New Zealand.

Information Requested
1. Documents identifying substances and additives permitted in fuel.
2. Records explaining approval and compliance processes.
3. Fuel quality monitoring reports and testing results.
4. Any records of complaints or concerns regarding fuel performance, smell, or mileage.
5. Documents outlining cost components of fuel, including additives, transport, and taxes.
6. Costing comparisons with the 2008 period in history.
Administrative
I am writing to advise you that MBIE will provide a response but needs to extend the time available to
answer your request. MBIE’s response will be sent to you no later than 23 June 2026, which is an
extension of 20 days.
The reason for the extension is that consultations necessary to make a decision on your request are such
that a proper response cannot reasonably be made within the original time limit.
If you wish to discuss any aspect of your request or this response, or if you require any further assistance,
please contact [email protected].
You have the right to seek an investigation and review by the Ombudsman of our decision to extend the
time limit. Information about how to make a complaint is available at www.ombudsman.parliament.nz or
freephone 0800 802 602.

Nāku noa, nā
