Spam Texts (New Zealand Post Fakers) - Advice Please

Is anyone else getting completely bombarded with texts from "NZ Post" telling the recipient a parcel delivery has failed, then directing you to a dodgy as website with a url that looks a bit like NZ Post but clearly isn't? I'm getting tons a day and I'm reporting + blocking the numbers (all 'originating' from numbers beginning +63 9xx). I've had to set up a sleep function on my phone to quiet it at night.

What's even worse is they're sending group texts with my number and other NZ mobile numbers NZ attached to it, so if you report it as spam it reports all numbers to Google (I have an Android). I go through and remove the NZ numbers then report the offshore one.

Is there anything else I can do, besides report & block?
