What this value means
Mandatory interest on money judgments (pre- and post-judgment, s 10) in New Zealand courts — NOT a self-executing B2B late-payment rate outside litigation. The statute itself fixes a rolling formula: base = average of the six most recent MONTHLY observations of the RBNZ B3 retail 6-month term-deposit rate, plus a 0.15-point premium (both substitutable by regulation; none made). The commonly repeated mechanics are WRONG: not the 90-day bank bill rate, no Order in Council, no fixed half-year periods, and the '5% prescribed rate' in older material is the pre-2018 Judicature regime. The per-annum simple rate converts to a daily effective rate and accrued interest CAPITALISES ANNUALLY (s 12(2)); the Ministry of Justice maintains the official online calculator (s 13). The rate moves with each monthly B3 release (July's observation was released 7 August 2026; next ~7 September) — re-verify monthly. RETRIEVAL: legislation.govt.nz and the RBNZ B3 page both block non-browser fetchers.
