Stress test disclosures due by 23 December 2026

The spot price risk disclosure (stress testing) regime requires certain participants in the wholesale electricity market to assess their financial exposure to hypothetical movements in electricity spot prices and report the results each quarter.

The disclosures for the first quarter of 2027 are due no later than Wednesday 23 December 2026, which is five business days before the start of the quarter to which the disclosure relates.

The stress testing regime applies to disclosing participants that consume electricity directly from the national grid or purchase electricity from the clearing manager, including those who will be disclosing participants during the period to which the disclosure relates.

Disclosing participants need to report their results to their Board and to the stress test registrar (NZX).

Aggregated stress test results from previous quarters are available on our website.
