Yes, some call it AV-plus, and some call it MMP-plus.
I call it MMP-plus because it's MMP but when you're electing on the local side, instead of using first past the post as we do, you use the ranked ballot, so you produce the locally elected MPs that way. That's the only difference.
But they also were quite fierce in their criticism of AV as a stand-alone reform where you just keep single member districts and use AV. I don't know what the compromise dynamics were whereby they must have seen a separate set of good reasons why having more general support—even if some of it is second preferences it counts for something—and they embraced it. I can't quite remember their reasoning. That was the only difference from MMP.
