Purchase Order — Template (New Zealand)

A Purchase Order — Template in New Zealand records the goods or services supplied, the amounts payable, and the payment terms between supplier and customer, consistent with the Companies Act 1993.

The Purchase Order is a cornerstone document in New Zealand business procurement. It establishes, in writing, exactly what the buyer wants, at what price, when, and where — before any goods change hands or any tax invoice is raised. This written record is essential for matching incoming tax invoices and delivery dockets to the original order, managing accounts payable, and preventing disputes over price, quantity, or specification.

New Zealand Purchase Orders operate within a specific legislative framework. The Contract and Commercial Law Act 2017 (CCLA) is the primary statute governing commercial contracts in New Zealand. The CCLA consolidated 11 previously separate commercial Acts into a single thorough statute, covering contractual remedies, misrepresentation, privity of contract, sale of goods, and electronic transactions. The CCLA replaced the Contractual Remedies Act 1979, the Contractual Mistakes Act 1977, the Illegal Contracts Act 1970, the Frustrated Contracts Act 1944, the Hire Purchase Act 1971, the Sale of Goods Act 1908, and several other Acts.

The Goods and Services Tax Act 1985 governs how GST of 15% applies to the supply of goods in New Zealand. The PO must clearly identify whether prices are quoted exclusive of GST (with GST at 15% payable in addition) or inclusive of GST. New Zealand's standard commercial practice is to quote prices exclusive of GST and separately show the GST amount.

The Consumer Guarantees Act 1993 (CGA) imposes mandatory statutory guarantees on goods supplied in trade or commerce — including acceptable quality, fitness for purpose, and correspondence with description — that apply regardless of what the PO says. These guarantees cannot be excluded in business-to-consumer transactions. In business-to-business transactions, they may be contracted out of in writing under section 43 of the CGA, provided it is fair and reasonable to do so.

New Zealand payment terms differ from those in Australia and the United Kingdom. The most common commercial payment term in New Zealand is the 20th of the month following invoice date — known as 'end of month' or 'EOM' terms — rather than the 30-day terms more common internationally.

A Purchase Order is needed whenever a New Zealand business purchases goods from a supplier and wants a formal written record of the transaction before delivery. The PO is particularly important in the following situations.

Regular procurement from suppliers: Businesses that regularly purchase stock, raw materials, equipment, or consumables should use Purchase Orders to document each transaction. This creates a clear audit trail for the three-way matching process (PO — delivery docket — tax invoice) used by accounts payable departments to authorise payment.

Large or high-value orders: For significant purchases, a PO locks in the agreed price, quantity, and delivery date before the supplier begins production or dispatch. Under the CCLA 2017, once accepted, the contract is formed on the PO terms, preventing the supplier from varying price or specifications unilaterally.

Purchases involving GST: A Purchase Order that clearly states prices exclusive of GST at 15% (with GST shown separately) and requires the supplier to issue a compliant tax invoice is essential for GST-registered buyers seeking to claim input tax credits under the Goods and Services Tax Act 1985.

Orders with quality or compliance requirements: Where goods must meet particular New Zealand Standards, health and safety requirements under the Health and Safety at Work Act 2015, or other specifications, the PO is the appropriate document to record those requirements and make them contractually binding on the supplier.

Suppressing supplier standard terms: Many suppliers attempt to supply goods on their own standard terms. A clearly worded Purchase Order that expressly excludes or overrides the supplier's terms is the primary mechanism for buyers to protect their position in the 'battle of the forms' under New Zealand contract law.

Government procurement: New Zealand government departments and public entities are required to follow the Government Procurement Rules (published by the Ministry of Business, Innovation and Employment — MBIE) and must use compliant Purchase Orders for any goods acquisition above relevant thresholds.

A well-drafted New Zealand Purchase Order should address the following key elements to be effective as a procurement and legal document.

Unique PO number: Every Purchase Order should carry a unique reference number quoted on all tax invoices, delivery dockets, and correspondence. This number is the linchpin of the three-way matching process used by accounts payable teams to authorise payment.

Party identification with NZBNs: Both the buyer and the supplier should be identified by their full legal names and New Zealand Business Numbers (NZBNs). The 13-digit NZBN is issued by the New Zealand Business Register and is increasingly used in commercial transactions. Including the supplier's NZBN assists with identity verification and reduces fraud risk.

Detailed item descriptions: Each line item should include a description, product code or part number (if applicable), quantity, unit of measure, and unit price exclusive of GST. Precise descriptions provide a clear basis for rejecting non-conforming goods under the Consumer Guarantees Act 1993.

GST calculation at 15%: The PO should show the subtotal exclusive of GST, the GST amount (15% of the subtotal under the Goods and Services Tax Act 1985), and the GST-inclusive total. This assists the supplier in issuing a compliant tax invoice and assists the buyer in verifying the invoice against the PO.

Delivery details: The delivery address, required delivery date in DD/MM/YYYY format, and any special delivery instructions should be clearly specified. New Zealand businesses commonly specify delivery in business hours from Monday to Friday, excluding New Zealand public holidays.

NZ payment terms: New Zealand standard commercial payment terms are the 20th of the month following invoice date. The PO should state the payment terms so that the supplier can price accordingly. Where late payment interest is to apply, the rate and conditions should be set out in the PO or in the underlying supply agreement.

Consumer Guarantees Act 1993 and Health and Safety compliance: The PO should confirm that goods must comply with the CGA statutory guarantees and applicable New Zealand Standards, and must meet health and safety requirements under the Health and Safety at Work Act 2015.

Governing law: The PO should state that it is governed by the laws of New Zealand, including the Contract and Commercial Law Act 2017, and that each party submits to the non-exclusive jurisdiction of the New Zealand courts.
