Yes. Bank of New Zealand connects through Akahu, the New Zealand open banking platform, so you can link your accounts and start syncing in minutes.

How often does BNZ sync to Zerosum?

Syncs are event-driven: Akahu notifies Redbark via webhooks and regular refreshes when new BNZ data is available, and your Zerosum updates soon after, within a few hours of a transaction posting, with no fixed polling schedule.

Is my BNZ connection read-only?

Yes. Akahu connections are read-only. Redbark can read transactions and balances, and can never move money or change your BNZ accounts.

Does Redbark store my BNZ data?

No. Redbark uses a pass-through architecture: your BNZ transactions are proxied live to Zerosum. We store consent records, encrypted tokens and minimal account metadata, never transaction amounts, descriptions or balances.

Is Redbark independently security tested?

Yes. Redbark was penetration tested in July 2026 by Project Black, a CREST-accredited Australian security firm, covering the web app, REST API, MCP server and admin console. The test returned zero critical and zero high-risk findings, and every finding raised was remediated and confirmed closed on retest.

Which Zerosum plan supports BNZ sync through Redbark?

Zerosum’s bring-your-own-provider bank sync is included with Plus and Pro, including the Pro trial. Redbark Developer is 30% off while your Zerosum connection stays active.

Will Zerosum duplicate my BNZ transactions?

Zerosum runs SimpleFIN imports through its normal review, matching and duplicate-prevention flow. You control which BNZ provider accounts are linked to each budget account.
