How we buy goods and services

New Zealand Post uses two approved purchasing methods:

  • Purchase Orders (POs)
  • Purchasing Cards (PCard)

Unless specific arrangements have been agreed in writing, payment to suppliers will only be made when one of these approved purchasing methods has been used.

Purchase Orders

Purchase Orders are our preferred method for buying goods and services provided on a regular or agreed basis.

There are two types of Purchase Orders:

Standard Purchase Orders
A standard Purchase Order is used for individual requests that require their own identifying number. For example, where a supplier provides multiple types of goods or services, or supplies different business units, a unique Purchase Order number is required for each request to enable tracking and approval.

Blanket Purchase Orders
A Blanket Purchase Order is used where goods or services are supplied under:

  • An individually negotiated agreement, or
  • An agreed arrangement for specialised goods or services provided to a specific business unit or group

Blanket Purchase Orders are typically valid for a defined period or up to an agreed total value.

Purchasing Cards (PCard)

The Purchasing Card (PCard) is New Zealand Post’s company credit card. It is issued to authorised staff who require a flexible way to purchase goods or services for business purposes.

The PCard may be used for:

  • One‑off purchases
  • Regular supply arrangements
  • On‑demand services where usage may be unpredictable

To accept PCard payments, suppliers must have VISA credit card facilities.

Purchasing methods overview

When supplying to New Zealand Post:

  • One‑off purchases are made using a Purchase Order
  • Regular provision of goods or services may use a Blanket Purchase Order or a standard Purchase Order
  • Occasional or on‑demand services under an agreed arrangement may use a Blanket Purchase Order
  • PCard may be used across all categories where approved
