It's just an OnlyFans ad. The numbers are always fake so you will never get a reply. If you do go on only fans they will just try and scam you out of money. They will never actually provide any escort services, they probably don't even live in NZ. If you are a high roller you may be able to actually have sex with them if you are willing to spend like 10k plus if you are willing to travel to them or fly them to you. It's just a scam to get you to sign up to her only fans really, which she has succeed in.
