I accidentally typoed my rego online once when renewing it, it was also a VW Golf (different year and colour but I wasn't paying attention)
Thankfully I DID realise when the confirmation email came thru. I rang up Waka Kotahi and they fixed it very quickly - told me it happens _all the time_ and at least I caught it early as it's a lot harder to fix when the label's been printed.
So yea, don't guess.
