Level playing field proposed Code amendments

Upcoming Open Closed Decision

Consultation

Following our first Level playing field consultation, we sought feedback on proposed Code changes necessary to introduce mandatory non-discrimination obligations.

The proposed amendments to the Code would impose principles-based non-discrimination obligations that the four large gentailers – Genesis, Contact, Meridian and Mercury – would have to follow.

This would prevent the gentailers from giving preferential treatment to their retail arms for hedge contracts. Instead, they would have to make these contracts available to all industry participants on effectively the same terms as they use when trading internally. This would ‘level the playing field’ so independent retailers and generators can better compete with the gentailers.

The non-discrimination obligations form part of a package of pro-competition interventions to boost competition, build confidence in the electricity market, and ultimately give New Zealanders better access to affordable electricity.

Note, in response to requests for additional time, we extended the closing date for submissions by one week to 5pm, Tuesday 2 December 2025.
