That Auckland Uni one needs to go back to the 70's and 80's era elections. Alt History FTW.
I love alternate-history stories, but I don't think we dare to put up scenarios from the 1980s, let alone the 1930s. We've had a certain amount of flak just for including those buttons that fill in the form with the party vote from MMP elections 1996-2008; not everyone agrees that this is a meaningful thing to try.
I'd be tempted to volunteer myself, if I hadn't already made my programming contribution to this particular topic.
Whether you're planning a better version of our simulator, or something a bit different, I'll be very interested to see what you come up with.
