Party and the Mana Movement not submitting lists was due to their forming an electoral alliance called Internet MANA. This alliance had to be registered as a separate party, but the individual component parties were not deregistered, and are thus listed as not having submitted a list. Internet Mana was deregistered in December 2014. Strategic voting Strategic voting refers to the incidence where voters split their voting between their party vote and their candidate vote. Partly to facilitate this, the two largest parties National and Labour usually "top up" their electoral candidates with list candidates, so that supporting a candidate of a minor party allied with their party will not reduce the number of seats that the major party wins, but supporting the minor party will increase the number of MPs who support their party in coalition. This is called "strategic voting" or sometimes "tactical voting". Strategic voting under MMP took place during the 1996 New Zealand general election when Richard Prebble contested the Wellington Central (New Zealand electorate) for ACT New Zealand. Shortly before Election Day, National Party Leader and Prime Minister Jim Bolger indicated to National Party voters that they should vote for Prebble rather than the National candidate Mark Thomas. This was to assist ACT in winning the electorate, and thereby being available to support a new National-led government. It seemed ACT's chances of entering parliament may have depended on this; Prebble won the seat, but ACT also ended up crossing the five percent threshold. In 1999, when Jeanette Fitzsimons contested the (usually National) seat of Coromandel for the Greens, it seemed that the Greens' chances of entering parliament were dependent on Fitzsimons' performance in Coromandel; in order to receive proportional representation, the party needed to either gain five percent of the national vote or win an electorate seat, and it appeared that the former option was unlikely. Labour Leader (and Prime Minister after the election) Helen Clark openly encouraged Labour supporters to give their constituency vote to Fitzsimons and their party vote to Labour. When normal votes had been counted, it appeared that Fitzsimons had been defeated in Coromandel by National's Murray McLean, but when special votes were tallied, Fitzsimons had a narrow lead. This guaranteed the Green Party seats in parliament regardless of whether it crossed the five percent threshold (as it eventually did). In several recent elections in New Zealand, the National Party has
