I've done my best to simulate the MMP formula, but it doesn't really work with inputs from just one party. Hence you'll find that Labour's default position is 31 MPs vs the 32 it actually got in 2014. Treat the total MP results as ±1. To play around with a complete set of numbers, try the Electoral Commission's calculator.
In calculating gender totals I've assumed that Andrew Little and Annette King will receive the first and second positions on the list.
At this stage only the first two List candidates are known (Andrew Little and Jacinda Ardern automatically get positions 1 and 2 as leader and deputy). I've also included David Parker, Sue Moroney and Trevor Mallard as list only candidates as per their current caucus rankings.
