Do you work with MuleSoft, Apigee, and WSO2?

Yes, we design, implement, and optimize API management on MuleSoft Anypoint, Apigee, WSO2, and Kong.

Can you build open banking APIs for our institution?

Yes, including account information and payment initiation APIs with compliant consent and authentication flows.

How do you speed up partner API onboarding?

Through self-service developer portals with sandbox environments, clear documentation, and standardized authentication.

Can you modernize our legacy core without a full rewrite?

API Integration & Open Banking Engineering in New Zealand

Banks, fintechs, and platform businesses run on APIs — and every unreliable integration becomes a partner escalation. Hurain Technologies designs, builds, and secures API ecosystems, from open banking connectivity to enterprise API management, so your partner integrations are fast to onboard, well-governed, and secure by default. In New Zealand, that means building to the technical expectations of Asia-Pacific: New Zealand assesses crypto-asset activity under the existing Financial Markets Conduct Act rather than a dedicated crypto licensing regime, with the Financial Markets Authority (FMA) determining case by case whether a token or service is a regulated financial product.

New Zealand Regulatory Landscape

What api integration services buyers in New Zealand need to know

New Zealand assesses crypto-asset activity under the existing Financial Markets Conduct Act rather than a dedicated crypto licensing regime, with the Financial Markets Authority (FMA) determining case by case whether a token or service is a regulated financial product.
Payment system oversight and financial stability sit with the Reserve Bank of New Zealand (RBNZ).
Open banking-style data-sharing standards are developing under New Zealand's evolving customer and product data framework.
We build to current FMA and RBNZ expectations and flag classification-sensitive features for review by New Zealand legal counsel given the case-by-case approach.

The Challenge

Problems we see teams struggling with

Slow partner and third-party onboarding

Without a proper API gateway and developer portal, every new integration takes weeks of custom engineering.

Inconsistent API governance

Multiple teams shipping APIs without standards creates versioning chaos and security gaps.

Legacy core system bottlenecks

Monolithic cores can't expose modern, well-documented APIs without a middleware layer.

Open banking compliance pressure

PSD2/open banking-style mandates require secure, standards-compliant APIs with strong consent and auth flows.

No visibility into API usage and abuse patterns

Without centralized gateway analytics, teams often don't know which partners are hitting rate limits, which endpoints are being scraped, or where latency is actually coming from.

Breaking changes disrupting live partner integrations

APIs shipped without a versioning strategy force partners into painful, uncoordinated migrations every time the underlying system changes.

Our Approach

How we deliver api integration services in New Zealand

API strategy & governance

API design standards, versioning policy, and lifecycle governance so every team ships consistent, secure APIs.

Open banking API development

Account information and payment initiation APIs built to open banking standards with OAuth2/OIDC consent flows.

API gateway & management platforms

Implementation and consulting across MuleSoft, Apigee, WSO2, and Kong for traffic management, throttling, and analytics.

Middleware modernization

Wrapping legacy cores with modern, well-documented REST/GraphQL APIs without a risky core rewrite.

Developer portal & partner onboarding

Self-service developer portals with sandbox environments that cut partner integration time from weeks to days.

API security engineering

OAuth2/OIDC, mutual TLS, rate limiting, and API-specific threat protection against abuse and data exfiltration.

Versioning and deprecation strategy

A formal API lifecycle policy that gives partners predictable migration windows instead of surprise breaking changes.
