Even more essential

A New Zealand MMP election does two things:

1. It decides which parties will be eligible to be allocated seats in parliament.
2. It allocates those seats in parliament in proportion to (eligible) voter support.
   BUT
   Only people who voted for a winning party in step 1 may take part in step 2.

I think that every voter should have a say at step 2.

Two choice party voting does that, without the need to change the threshold percentage or any other aspect of the MMP system.
