Newcastle Permanent Building Society

Newcastle Permanent Building Society is a customer-owned Australian authorised deposit-taking institution (ADI) founded in 1903 and headquartered in Newcastle, New South Wales.

In March 2023 it merged with Greater Bank to form Newcastle Greater Mutual Group (NGM Group), one of Australia's largest customer-owned banks, while Newcastle Permanent continues to operate as a consumer brand. As a regulated ADI it is a data holder under Australia's Consumer Data Right (CDR / Open Banking) and exposes a live, public, unauthenticated Product Reference Data (PRD) API conforming to the Data Standards Body Consumer Data Standards, alongside an NPBS Innovation Sandbox and Marketplace developer portal.

Newcastle Permanent Building Society publishes 9 APIs on the APIs.io network, including Banking Account Balances API, Banking Account Direct Debits API, Banking Account Scheduled Payments API, and 6 more. Tagged areas include Financial, Banks, Open Banking, CDR, and Consumer Banking.

Newcastle Permanent Building Society’s developer surface includes getting-started guide, documentation, API reference, sandbox, authentication, support, and 23 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/newcastle-permanent: open an issue to ask a question, or submit a pull request to add artifacts.
