So the New Zealand Racing Board has been forced to contact all its Australian clients and tell them their TAB accounts are closed.
That alone will cost the NZRB millions in lost turnover but what is impossible to calculate is how much it will cost in turnover from New Zealand punters who are travelling or living part-time in Australia.
As of yesterday no computer with an Australian IP address was able to access the New Zealand TAB site.
Which means any Kiwi punter heading to Australia intending to use a local computer or their mobile phone through a Wi-Fi connection will be blocked from using the TAB site, and therefore having a bet. The one loophole could be New Zealanders travelling to Australia but using their mobile data on a roaming plan, who may still be able to access the TAB site.
NZRB now have to work out how to navigate the problem long-term as it looks certain, with their close Australian ties, they weren't intended to be among the restricted operators but legally they are. They could apply for an Australian operations licence, which are not cheap, or for dispensation from the block.
But for now, as racing's golden spring approaches, the New Zealand TAB is off limits to those living in Australia or travelling there, which means they also can't watch New Zealand racing on many phones or computers.
