The MMP simulator can be run on all the general elections in this jurisdiction.

“Acc?” stands for missing data (namely races entered as having been won by acclamation when in fact the results are unknown), while “Minis.” shows the number of ministerial by-elections.

A small handful of by-elections that did not really occur was added to this database to record when someone’s election was overturned and the seat was handed over to the challenger who had lost. The results for several by-elections are missing for this jurisdiction.

Up until the middle of the 20th century, unseating a member was commonplace and the mechanism to challenge someone’s election seems to have been very lax when viewed through presentist lens, as many by-elections were held merely because the challenger — often the government or the defeated incumbent — did not like the result. What’s more, newly appointed ministers had to resign and run in a ministerial by-election. Therefore, by-elections were far more frequent than they are today.
