Just came to the end of the signup offers. Did find things getting trickier as I got to the bottom of the list. Bookmaker.com told me they are unable to do sign up bonuses as per state law and when I challenged them on that they told me I couldn’t get a sign up bonus because I already have a Ladbrokes account.
Then Classic Bet have just told me they don’t accept customers from NZ, even though they have NZ contact numbers on their website.
My worst experience was with TAB who are almost impossible to contact, at least internationally, and have the most draconian verification process imaginable. They basically require me to fly to Australia and sacrifice vital organs to let me bet with them
Still, with sign up bonuses from the other websites, I’ve made $1250 over the last six or so weeks.
