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 Firefly III?

Syncs are event-driven: Akahu notifies Redbark via webhooks and regular refreshes when new BNZ data is available, and your Firefly III 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 Firefly III. 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.

Do I need a bridge script for BNZ?

No. Redbark implements SimpleFIN directly, which the Firefly III data importer supports natively. You paste one setup token and the importer handles the rest.

Why is my first BNZ import slow?

The importer backfills history in 44-day windows, and with no start date it begins at 1970. Set a start date in the importer and the first run drops to a handful of requests.

BNZ transactions in self-hosted Firefly III

The Firefly III data importer pulls BNZ accounts, balances and transactions straight from Redbark over SimpleFIN. Every transaction carries a stable bank-issued ID, so repeat imports reconcile instead of duplicating.

Get started

Sync BNZ to Firefly III in three steps

Connect BNZ

Link your BNZ accounts to Redbark through Akahu open banking, then generate a SimpleFIN setup token in Settings and name it after your Firefly instance.

Claim the token in the importer

Run the Firefly III data importer, choose the SimpleFIN import flow, and paste the setup token when it asks. The importer claims it once and keeps its own private credentials.

Set a start date and import

Give the importer a start date before the first run. Without one it walks history from 1970 in 44-day chunks, which makes the initial BNZ import very slow.
