RBNZ Prudential Returns and Reporting Requirements

Regulator Reserve Bank of NZ
Jurisdiction NZ
Status live
Applicability Platform

The Reserve Bank of New Zealand (RBNZ) requires registered banks to submit a comprehensive suite of prudential and statistical returns on a regular schedule. Requirements are set out in the Registered Bank Disclosure Statement regulations, the Banking Supervision Handbook, and individual Banking Supervisory Policy (BS-series) standards. Returns cover capital adequacy, liquidity, large exposures, mortgage LVR bands, connected exposures, and a range of statistical surveys used by RBNZ for macroprudential policy.

Key return series: BS1 (capital adequacy), BS11 (liquidity), BS13 (large exposures), BS19 (residential mortgage LVR), BS8 (connected exposures), the RBNZ Banking Survey (monthly, required by all registered banks), and RBNZ Payment Statistics (quarterly). The CFO is the accountable signatory for all prudential returns. RBNZ may take enforcement action for persistent reporting failures, including requiring a bank to hold additional capital.


Compliance register

This register maps every material reporting obligation to the platform control or institutional process that satisfies it. It is the static traceability layer for the Totara compliance report — dynamic data (module build status, test evidence, control test dates) is overlaid at runtime.

Scope legend

Symbol Meaning
🤖 Automated Platform enforces or performs the obligation. Primary control mode is GATE, AUTO, CALC, or ALERT. Human action is not required in the normal case.
📊 Evidenced Platform captures the evidence trail automatically. Human compliance decision sits on top. Primary control mode is LOG.
🏛 Institutional Obligation is met by a process entirely outside the platform — training programmes, board governance, HR, legal. Platform may generate evidence inputs but does not own the process.
N/A Obligation does not apply to this deployment configuration.
