Explanatory note

This note is not part of the regulations, but is intended to indicate their general effect.

These regulations, which come into force on 2 October 2017, amend the Engine Fuel Specifications Regulations 2011. The amendments—

  • reduce the maximum allowable sulphur content in petrol from 50 parts per million to 10 parts per million. This change takes effect on 1 July 2018:

  • introduce a total oxygen limit of—

    • 2.7% mass for petrol blended with not more than 5% volume ethanol:

    • 3.7% mass for petrol blended with more than 5%, but not more than 10%, volume ethanol:

  • increase the limit for methanol in petrol from 1% to 3% volume:

  • increase the limit for biodiesel in diesel from 5% to 7% volume:

  • introduce requirements for petrol blended with more than 70%, but not more than 85%, ethanol (defined as fuel ethanol E85):

  • make other minor changes to the regulations (such as prescribing additional test methods for certain fuel properties).

The regulations incorporate by reference various standards, procedures, and test methods. The incorporated material has no effect until it is made available for inspection at the head office of the Ministry of Business, Innovation, and Employment (see section 35(2) to (5) of the Energy (Fuels, Levies, and References) Act 1989).

Regulatory impact statement

The Ministry of Business, Innovation, and Employment produced a regulatory impact statement in June 2016 to help inform the decisions taken by the Government relating to the contents of this instrument.

Issued under the authority of the Legislation Act 2012.

Date of notification in Gazette: 24 August 2017.

These regulations are administered by the Ministry of Business, Innovation, and Employment.

1 For regular and premium grade petrol in summer, a minimum E70 of 20% is permitted. Petrol that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season.

2 For regular and premium grade petrol blended with more than 1% volume oxygenates, the E70 maximum is increased by 1% per 1% volume oxygenates in the blend.

3 For regular and premium grade petrol blended with more than 1% volume oxygenates, the flexible volatility index maximum allowed is 115.0 summer; 120.0 autumn and spring; 130.0 winter. Petrol that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season.

4 For regular and premium grade petrol blended with more than 1% oxygenates, the maximum vapour pressure allowed is Auckland and Northland: 72 kPa summer, 87 kPa autumn and spring, 97 kPa winter; rest of North Island: 77 kPa summer, 87 kPa autumn and spring, 97 kPa winter; South Island: 82 kPa summer, 92 kPa autumn and spring, 102 kPa winter. Petrol that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season.

5 Regulation 8(3)(c) provides that ethanol must comply with Schedule 4 (requirements for denatured ethanol for blending).

6 Regulations 10(a) and 17(2)(a) provide that, in the case of the biodiesel component of any blend of diesel and biodiesel, the maximum viscosity at 40ºC is 6.0 mm2 per second.

7 Regulations 10(b) and 17(2)(b) provide that, in the case of the biodiesel component of any blend of diesel and biodiesel, the minimum cetane number is 47.

8 Regulation 10(c) provides that, in the case of the biodiesel component of any blend of diesel and biodiesel sold by retail sale, the minimum oxidation stability is 10.0 hours.
