A guide to procurement at IAWAI
We work with suppliers to help keep water flowing for Hamilton and Waikato. Find out how IAWAI buys goods and services, how we choose suppliers, what you need to do before working with us, and where to view current tender opportunities.
How we choose suppliers
IAWAI works with many suppliers to keep our water flowing, and to improve and add to our assets and infrastructure.
In procuring products and services, we consider price, but also factors such as capability, approach, environmental, social, cultural, and economic benefits that can be generated.
IAWAI has a procurement policy that sets out preferred procurement approaches based on financial thresholds and the nature of the goods or services required. This may include formal tender processes, secondary procurement through preferred supplier panels, or obtaining quotes.
If you're supplying goods or services
You must complete onboarding through our Eftsure process and accept our standard Purchase Order terms and conditions before delivering any goods or services.
Eftsure supplier verification
IAWAI uses Eftsure to verify payments we make to suppliers. This platform helps IAWAI securely pay our suppliers using the right bank details.
By using Eftsure’s third-party supplier verification, we make sure the outgoing payments can’t be intercepted by cybercriminals or fraudsters.
If you have received a request from IAWAI to validate your details through Eftsure, you must complete the verification process.
If you have any questions about your supplier onboarding application, please contact your IAWAI representative. If you experience technical issues with the Eftsure portal, such as trouble logging in or uploading documents, please email support@eftsure.com.au for assistance.
Common questions about Eftsure
What is Eftsure?
Eftsure is a business to business (B2B) payment protection service that we use to streamline and protect our supplier onboarding process. Whether a threat originates from within our organisation, a supplier or a third-party organisation, Eftsure helps protect our supplier base and reduces the risk of payment error, fraud attempts and cyber-crime. Eftsure’s alert system helps us avoid paying fraudsters instead of the correct recipients, lowering your risk of delayed payment.
What is our verification process?
Depending on whether the supplier has already been verified by our payment protection partner, Eftsure, you may receive a digital invitation linking to an online form. This process, powered by Eftsure, helps make verification easier and minimises the legwork of ad hoc documentation requests or paperwork. It also helps protect your company and IAWAI from cybercrime attempts.
Can I skip Eftsure and still be an IAWAI supplier?
No. To protect our supplier base and reduce the risk of payment error, all suppliers must be verified through the Eftsure process. If a supplier refuses, they will not be approved as a supplier.
Do existing suppliers still need Eftsure?
If you’re an existing supplier to IAWAI, you might still need to register with Eftsure. This is to protect both of our organisations from risks like external cybercrime and employee error during the payment process. Once your details are verified by Eftsure, you will not need to be re-verified with any of your other customers who use Eftsure’s solution, although other companies may choose to request additional information or documentation.
Is it safe to share my bank details with Eftsure?
Yes. Eftsure follows best practices for securing data and its systems. It has been vetted by numerous industry leaders and is regularly audited and penetration-tested by external security specialists.

How can I safely share and verify my account info?
The communications you receive will include a link to register with Eftsure. The process asks you to submit details like your NZBN, trading name and company address, as well as asking you to confirm payment information. You’ll have two options for confirming your bank account details:
Online verification tool (bank link)
This allows you to select your relevant bank account details from your bank without you needing to enter in the bank account details manually. Suppliers can securely and automatically verify their payment details through the Eftsure Bank Link (Yodlee) option, where the underlying financial system is leveraged to securely verify the Supplier’s nominated account name and account number against the New Zealand Business Register and New Zealand Business Numbers. The supplier credentials are not seen or stored by anyone at Eftsure, Yodlee or your customer’s organisation. (If the account name does not match your registered business name, you may still receive a phone call for security purposes.)
Phone call
One of our fraud verification analysts will contact you and undertake an initial screening validation process related to information on the submitted online form. The fraud verification analysts will then complete a two-way, interactive account number verification process to verify the account number, account name and other details about your business.
Purchase order (PO) numbers
When working with you, we will supply you with a purchase order (PO) number, and often a contract number. It is your responsibility not to supply goods and/or services unless you receive a valid purchase reference.
We will not be able to process your invoice for payment without a valid purchase order number.

We list our tender opportunities on the New Zealand Government Electronic Tenders Service (GETS).
