If you’re a current supplier or are interested in becoming a supplier, find out how we buy goods and services.

Our buying approach

All our buying activities are made within the framework of:

  • the five Principles of Government Procurement
  • Government Procurement Charter 
  • Government Procurement Rules
  • Natural Hazards Commission Toka Tū Ake Delegations Framework policy.

How we work

Our preference is to use Government collaborative contracts, our own internal panel arrangements, or existing supply contracts where appropriate. In some cases, use of the Government collaborative contracts is mandated.

Other contract opportunities with a total estimated value of $100k or more will generally be advertised through the Government Electronic Tenders Service run by the Ministry of Business, Innovation and Employment (MBIE).

To register for this free service visit the Government Electronic Tenders Service website(external link).

Getting paid

Our payment terms

Our standard payment terms apply if there is no contract in place, or no other payment terms are specified. Standard payment terms mean payment is made by the 20th of the month after we have received your invoice. For example, if we receive an invoice in January, it will be paid on 20 February.

NHC Toka Tū Ake will endeavour to pay all invoices within 10 days of the invoice being entered into our system, regardless of the agreed payment terms.

Our payment method

Our payment method is electronic funds transfer (EFT). This means payments can be deposited directly into your designated bank account. We will endeavour to email a remittance advice confirming the EFT payment on the day the payment is made.

Changing your payment method

To change your payment method, we need to verify your bank account details. You can do this by sending us:

  • a bank deposit slip (a scanned copy will be fine), or
  • a screenshot showing your bank account details (please block out any account activity).

The screenshot must have both the bank's logo and the account number. Make sure the bank account you use on the invoice is the one we will be verifying.

Working with us

Keeping your details up to date

If you change:

  • your bank account information

please email us at  so we can make the necessary changes.

Supplier feedback and complaints

We manage supplier feedback and complaints according to the "Guide to supplier feedback and complaints" published by MBIE.

Invoicing us

We operate a purchase to pay system to approve, manage and make payment for all purchases. All purchases from NHC Toka Tū Ake must have a valid purchase order number.

You should receive the purchase order number by email before the goods or services are delivered. 

Tips to make sure your payment isn't delayed

  • Submit a complete and accurate invoice, for example one that meets the requirements of the Goods & Services Tax Act 1985.
  • If your business is GST-registered, include your GST number and the words "Tax Invoice".
  • Include the name of your NHC Toka Tū Ake contact who requested the goods and services as well as the purchase order number. 
  • Make sure the invoice matches the purchase order exactly, including what was delivered, unit of measure, quantity and unit price. 
  • Correct any discrepancies or changes before sending your invoice.

Sending us your invoices

We prefer to receive a PDF of your invoices electronically to our Accounts Payable team at

If you are unable to send your invoice electronically, you can send it to: Natural Hazards Commission Toka Tū Ake, Accounts Payable, PO Box 790, Wellington 6140.
