Does anyone have a list of banks and the way to find their bill payee forms?

I have seen a bank's form which a business can use to submit their reference formats. So if a customer of that bank tries to use internet banking to pay the business, the internet banking transfer form can mandate rules about the reference such as "Must be 7 digits" etc before they will process the payment no matter what bank it goes to.

I understand each bank has their own form which the business must fill out - so am looking for a list or a way to find them all that might be quicker than googling. As a non-kiwibank customer for example, i dont know what they call the function in their internet banking of paying a business that has registered billing info with kiwibank. BNZ calls it "Pay bills"
