NZ: Building Societies Act 1965¶

Applicability	Platform

The Building Societies Act 1965 governs the registration, governance, and operations of building societies in New Zealand. Building societies are mutual financial institutions that may accept deposits and make mortgage loans to members. They are regulated by RBNZ and, where they accept deposits, are subject to the Deposit Takers Act 2023 framework.

The Act covers: registration and constitution, governance (committee of management), member rights, accounts and audit, amalgamation and conversion (to company or registered bank), and winding up. Obligations under the Act apply to the building society entity itself — not to the technology platform it operates on.

This regulation is relevant to the Totara platform where a licensed building society deploys the platform as its core banking and compliance infrastructure. In that context, the platform satisfies the building society's prudential, AML/CFT, consumer, and payments obligations through the same module set used for any deposit-taking institution.

Compliance register¶

This register maps material obligations under the Act to platform controls or institutional processes. Most obligations are structural or constitutional — they apply to the building society entity, not to the platform. Platform obligations arise from the building society's activity as a deposit taker and lender, which are governed by the DTA 2023 framework and standard platform modules.

Building society banking operations are fully automated through the standard platform module set. Constitutional and governance obligations are institutional. Structural obligations (registration, rules, AGM) are N/A for the platform.

No policies currently reference this regulation directly. Building society clients are subject to the full AML, consumer credit, prudential, and privacy policy suite applicable to all deposit takers. See nz-dta-capital, nz-dta-disclosure, and nz-amlcft-act for the primary applicable registers.
