Improving payment times
From 1 July 2025, Auckland Transport (AT) will scan all supplier invoices that are sent to invoices@at.govt.nz . This is to check if they meet our document requirements. If they do not, the invoice will not be processed for payment. Instead, it will be automatically returned to the sender with an explanation of why and suggested actions to take.
An invoice should have:
an approved purchase order (PO) number
the words ‘Tax Invoice’ in a prominent place (if GST registered)
the name and GST number of supplier (if applicable)
the date of issue
the name and address of the recipient (for example, Auckland Transport)
a description of the goods or services provided
the quantity or volume of the goods or services provided.
Fairness to our supplier partners
Parked invoices (those that cannot be paid due to non-compliance) add up to millions of dollars not being paid on time to suppliers every year. The time taken to fix parked invoices by suppliers and our teams also adds up and is wasted effort.
We chose to make this process better and payments quicker by rejecting incomplete invoices at the start. Our teams are very keen to work with you to get this process right to reduce payment delays and support your cashflow. For more information go to Purchase order & invoicing processes .

Read and acknowledge the updated 2023 Supplier Code of Conduct
The Auckland Transport Supplier Code of Conduct is the foundation document requiring commitment from our suppliers to best practice relating to social, environmental, ethical and financial responsibility. The scope of the Code includes suppliers’ parents, affiliates, subsidiaries and subcontractors.
AT’s first Supplier Code was published in 2019. Following review of the Supplier Code between February 2023 and July 2023, a number of updates have been identified and have been incorporated into a revised 2023 version, which has now been approved by the AT Board.
Suppliers are required to commit to the expectations under each of the seven principles detailed in the 2023 Supplier Code, as a condition of doing business with AT.
Full details on the 2023 Supplier Code and what actions we need all our suppliers to take.

Improvements to the purchase order process
We are making it easier for our suppliers to work with us by initiating improvements to our Purchase order (PO) requisitioning process for all purchases of $25,000 or less.
From August, AT will automatically send out (upon approval) an email with a PDF copy of the Purchase order containing the PO number and line-item details with an agreed PO value. This email will be sent to the email address we have captured for each of our suppliers’ Accounts Receivable teams, as well as the supplier contact for that purchase.
The PO number, line-item reference(s) and detail of the goods and/or services provided should always be added to your invoice to ensure prompt payment. For more information on our Purchase order and invoicing processes, please click on the link below.

All invoices need to be submitted to invoices@at.govt.nz by close of business (COB) Monday 13 December (and approved by COB Friday 17 December) to make the last payment run on Monday 20 December. Please allow enough time for processing and approvals to take place.
