I'd contact Ansett Aviation Training (the organisation where the sims are) and ask them - I'm certain your question would not be the first they've had on that subject.
Even if they don't have any in-house TREs, they'll more than likely know where to find them.
Ask for the training manager if the receptionist can't help.
Good luck.
Oh...and if you have no luck with them, email the Air New Zealand training department. Auckland is alot closer than Europe.
