Status: Key Capital Review changes were brought into effect on 1 October 2021 via the new Banking Prudential Requirements (BPRs). Further changes will be gradually phased in. Consultation on Capital Review disclosure changes is currently open.
Consultation period: 2017- 2022
16 March 2022
Capital instruments for mutual banks are being considered. Please see here for more information:
22 February 2022
We are consulting on changes to the information that New Zealand-incorporated registered banks must publish in their six-monthly disclosure statements.
The main changes are to introduce ‘dual reporting’, which was one element of the Capital Review final policy decisions published in December 2019. Dual reporting refers to additional information that a bank would have to provide if it is accredited to use its own internal models to calculate risk-weighted assets (RWAs). This would show the bank’s RWAs recalculated using the standardised approach, alongside the modelled RWAs that the bank calculates to comply with minimum capital ratios.
We are also proposing some other additions to modelling banks’ disclosure requirements, to provide greater clarity around changes to their capital ratio calculations that came into force on 1 January 2022.
In addition, we are consulting on some other minor additions to disclosure statements for all New Zealand-incorporated banks, whether or not they are accredited to use their own risk-weighting models.
We are proposing that these changes would take effect for disclosure statements with reporting dates of 30 September 2022 or later.

17 June 2021
We published the final requirements for bank capital adequacy, outlined in new Banking Prudential Requirements (BPR) documents. The new rules implement the decisions made during the Capital Review and a comprehensive, five-year project, to restructure how the capital adequacy rules are written and presented.
The new framework increases the amount of capital banks must have, which will make the banking system safer for all New Zealanders. Increases in capital will be phased in over a seven-year period, starting from July next year. Other changes will be phased in from 1 October 2021 onwards.
Links to the new BPR documents, as well as a number of documents that describe how the framework will operate are available below. Links to the submissions the Reserve Bank received, and a Response to Submissions are also available below:

5 May 2021
The Exposure Draft consultation for the Capital Review implementation closed on 31 March 2021. We received feedback across a range of topics and intend to publish the final Banking Prudential Requirements (BPRs) documents, which implement the Capital Review, in early June.
Some of the feedback we received in the submissions asked for changes in the timetable for implementing the Capital Review. The following decisions were communicated in the May Financial Stability Report:
- The formal start date for implementing the new BPRs will be extended from 1 July 2021 to 1 October 2021. This will provide banks a longer period after the final documents are published to adjust systems and processes for the new framework
- The Reserve Bank intends to recognise Tier 2 instruments issued in accordance with the new BPRs after the BPRs are published, but before the 1 October date. We will provide details about how this will work when the BPRs are published in June.
- The start date for the derecognition of existing non-compliant capital instruments will be extended to 1 January 2022. This is an extension of six months and helps provide more time for banks to prepare for issuing new instruments.
- All other implementation dates will remain the same as previously communicated, including the 1 January 2022 introduction of an output floor set at 85% of the outcome under the standardised approach for banks accredited to use internal models (IRB banks) for calculating risk weighted assets.
All other responses to the feedback will be published with final BPRs in June. We will be writing to banks to inform them of these decisions and a copy of the letter will be available here:

17 November 2020
The Reserve Bank opened consultation on the details for implementing the final Capital Review decisions announced in December 2019.
Some of the most significant changes in the consultation include implementing the new rules for instruments that make up a bank’s capital, and consulting about the responses the Reserve Bank would take if a bank does not meet capital buffer requirements. The Reserve Bank is not seeking feedback on December 2019 policy decisions.
More information and consultation material is available on the Consultation on exposure draft for Capital Review page.
11 November 2020
The Reserve Bank announced a further delay in the start of increases in bank capital until 2022 to allow banks continued headroom to respond to the effects of the COVID-19 pandemic and to support the economic recovery. The changes mean the increase in the Prudential Capital Buffer will not begin until July 2022. The Reserve Bank will reconfirm this timing near the end of 2021, and will consider making further amendments to the timing if the conditions warrant it. Other aspects of the capital reforms will proceed from 1 July 2021, including the new rules around capital instruments.
Full details are available on the the news release page.
16 March 2020
In response to the impacts of COVID-19 and to support credit availability, the Bank has decided to delay the start date of increased capital requirements for banks by 12 months - to 1 July 2021. Should conditions warrant it next year, the Reserve Bank will consider whether further delays are necessary.
Full details are available on the news release page.
