nbroad:
I added my card to Apple Pay, which is an "Airpoints Standard Visa" to phone and watch.
All went fine, but I got a notification on my Apple Watch saying "your Kiwibank AirNZ Low Fee Visa has been added to your Apple Watch".
I thought that's weird, maybe I added the wrong card - double checked I had it right.
I then went to the local bakery to try it out, worked fine and came out of my "Airpoints Standard Visa", but the transaction history in Apple Wallet shows "Kiwibank AirNZ Low Fee Visa".
This appears to be just a cosmetic issue but maybe a card description mapping issue? I do have another "Airpoints Low Fee Visa" for joint household expenses, but didn't add this to Apple Wallet.
If you remove and re-add your card it should be fixed now.
