Sending Invoices to the project

Interim Invoicing arrangements

For the months of July, August and September 2017, the project will continue to process invoices using Auckland Transport's accounts payable system.

Please see the below for invoicing instructions:


From October 1, 2017, the project will stand up its own accounts payable function:

All other rules remain unchanged:

When you are ready to send us your invoice please: 

  1. Send a single PDF copy to or as per the above tables
  2. Ensure that your company name is in the subject line of the email
  3. Clearly reference the PO # on the front of the invoice
  4. Attach exactly 1 attachment to that email (emails with more than one attachment will be disregarded). If you do require supporting information on the invoice, these should be pages 2 (and so on) of the pdf.


Payment will be made via an electronic bank transfer into your nominated bank account.

Invoices will be paid on the 20th of the month following the date of the invoice unless alternative payment terms have been prescribed on your purchase/contract order number. For example, monthly services provided in January with an invoice dated:

  • 31 January and received by 5 February will be paid on 20 February
  • 1 February and received by 5 February will be paid on 20 March
