An election for the parliamentary leadership of the New Zealand National Party by its caucus was held on 14 July 2020, after incumbent Todd Muller resigned earlier that day citing health reasons. Judith Collins became leader of the National Party and of the Opposition of New Zealand.

The New Zealand National Party, shortened to National or the Nats, is a centre-right New Zealand political party that is the current ruling party. It is one of two major parties that dominate contemporary New Zealand politics, alongside its traditional rival, the Labour Party.
