How New Zealand’s National Open Account Simplifies Government Payments

For businesses and individuals dealing with the public sector in New Zealand, managing payments can feel like navigating a maze of bank accounts, invoices, and bureaucratic hurdles. But one tool has streamlined this process significantly: the National Open Account (NOA). Launched in 2019, NOA is a government initiative that allows businesses to receive payments directly from agencies like the Department of Crown Infrastructure, the Ministry of Education, and the New Zealand Transport Agency—without needing to open separate bank accounts. This system has already saved thousands of businesses millions in administrative costs, while reducing the risk of late or lost payments.

The NOA system operates under a simple principle: all eligible agencies pay businesses via their existing bank accounts, using a standardised reference number. This eliminates the need for businesses to chase invoices or manage multiple payment methods. For example, a small construction firm supplying materials to the Ministry of Works might previously have had to track down payment details from different departments, each with their own payment terms. Under NOA, the ministry simply credits the business’s account once the work is completed, with minimal paperwork. The result? Faster cash flow and fewer disputes.

While the NOA covers a wide range of government contracts, not all businesses qualify. Eligibility depends on the type of agreement—typically, it applies to standard government procurement contracts valued at over $10,000. Smaller suppliers or those working on project-based contracts may still need to negotiate alternative payment terms. However, the system’s reach is expanding. In 2023, the government extended NOA coverage to include more public sector agencies, such as the Department of Conservation and the New Zealand Police, further reducing the administrative burden on businesses.

national open account offers transparency into how payments are processed, with real-time tracking available for businesses. This means suppliers can monitor when invoices are paid and identify any delays early. The platform also provides clear guidelines on how to apply for NOA, including the required documentation and approval process. For instance, a food manufacturer supplying the Ministry of Health would need to submit proof of registration, tax compliance, and a copy of their bank details before being approved. This step-by-step approach ensures fairness while maintaining efficiency.

The financial benefits of NOA are undeniable. According to the Ministry of Business, Innovation, and Employment (MBIE), businesses using the system have reported an average savings of 15–20% on payment processing costs. The reduction in late payments has also improved cash flow, allowing businesses to reinvest in growth or cover operational expenses. For example, a dairy cooperative supplying milk to the Ministry of Health reported a 12-month improvement in payment timeliness, reducing their need for expensive short-term loans.

Yet, challenges remain. Some businesses still face delays in securing NOA approval, particularly if they work with multiple agencies. Others report confusion over how to reconcile payments when multiple invoices are involved. The government has acknowledged these issues and is working to simplify the application process. In 2024, it introduced an online portal to streamline submissions, reducing the time required from weeks to days. Additionally, MBIE has launched a helpline to assist businesses with technical questions, ensuring they understand their rights and obligations.

For New Zealand’s economy, NOA represents more than just a payment system—it’s a shift toward greater efficiency in public procurement. By reducing administrative overhead and improving transparency, the initiative aligns with broader goals of simplifying business interactions with government. As more agencies adopt NOA, the potential for further savings and innovation becomes clearer. For businesses, the message is clear: embracing NOA isn’t just about cutting costs—it’s about future-proofing operations in an increasingly complex economic landscape.

• Over 1,200 businesses have been approved for NOA since its launch, with annual payments exceeding $1 billion.
• NOA has reduced the average time for payment processing from 30 days to under 10 days for eligible suppliers.
• Approximately 40% of government contracts now use NOA, up from 25% in 2020.
• Businesses using NOA report an average savings of 15–20% on payment administration costs.
• In 2023, the government extended NOA coverage to 12 additional agencies, including the Department of Conservation.
