Agree this number is a crock of shit and the method for calculating it is totally illogical as you point out. It is not correlated to punter losses in any substantive way. With something like 90% of overseas bookies paying GST on NZ punter losses, they should be able to get a reasonably accurate assessment of those from the IRD but seem to prefer to float around these completely unfounded figures to make their case for Geo-blocking, not that that is likely to do much good anyway as you also say. It may be a negative on overall revenue.
