There's an ATR 600 sim in Singapore and Toulouse, with the 500 sims in Auckland, Toulouse and Johannesburg. I might have missed one though.
No endorsement training is done in Auckland though, as ATR provide the Skywest/VARA training themselves and the NZ sim is not owned by them. Word from crew there is it isn't the initial endorsement that's the hold up, it's the later line training meaning they're sitting around for quite some time.
