New Zealand has Mixed Member Proportional (MMP) where you vote for a local representative and also a party. There are a fixed number of local representatives and the rest of the 120 available seats are made up by the total party vote. So if you won 10 seats but 25% of the party vote you would have 10 representatives and 20 list/party MP's. It has also worked very well to give third parties more power and help keep the two main parties closer to the political center.
