Are [employer]’s surcharges covered?

Some employers choose to cover surcharges over and above their ACC requirement. If your patient does not know if their employer covers this portion it may be best to charge in accordance with your policy and procedures. Wellnz will reimburse them if entitled.

Alternatively you can call the Wellnz mainline on 0508 465 879 and one of our staff members will be able to advise whether the surcharge is covered.

How are payments made to providers?

Payments received in the current month will be paid the week of the 20th of the following month. Wellnz act on the behalf of the employer. All authorised invoices in that month require approval by the employer. Wellnz then release payment the week of the 20th.

Do I need a purchase order for an invoice?

For work related injuries – you can simply use the claim number. This can either be the ACC claim number (two letters followed by five numbers) or the Wellnz claim number (two letters followed by six numbers).

For non-work injuries – you need to be sure to bill ACC, not Wellnz. Use the 7 digit purchase order number, the service code and the ACC claim number (11 digit number). If you’re unsure of these details, be sure to contact Wellnz.

I need a remittance for a payment I received.

For remittance requests, send these to, be sure to include relevant information including payment dates and amounts. Remittances should go out automatically after a payment is made. If you haven’t received one, we may need to update your email address in our system. Let us know by emailing Please check junk mail for remittances as the attachments can sometimes get caught up in your email security.

I’m new to working with Wellnz, how do I get set up?

We’re pleased to be working with you! Most details we need to set you up as a creditor, will be on your invoice (business name, address, contact details, gst number, bank account number).
