The history of tennis in New Zealand dates back to the 1870s, the decade when the development of modern tennis began.
 The first "New Zealand Tennis Championships" were played at Farndon in Hawkes Bay in 1886.
 New Zealand Lawn Tennis Association (NZLTA) was formed at a meeting held in Hastings in December 1886.
 Shortly after its inauguration, the New Zealand Association became affiliated with the Lawn Tennis Association (England).
 In 1904 New Zealand Lawn Tennis Association amalgamated with six Australian state tennis associations to form the Lawn Tennis Association of Australasia.
 New Zealand Lawn Tennis Association played a significant role in the origin of the Australian Open.
 Lawn Tennis Association of Australasia created the tournament called "The Australasian Mens Championships" (which later became Australian Open) in 1905 and was first played in Warehouseman's Cricket Ground and it was decided that championships would be hosted by both Australian as well as New Zealand venues.
 New Zealand hosted the championship twice— Christchurch (1906) and Hastings (1912).
 The geographical remoteness of both the countries (Australia and New Zealand) made it difficult for foreign players to enter the tournament.
 In Christchurch in 1906, of a small field of 10 players, only two Australians attended, and the tournament was won by a New Zealander (Tony Wilding).
 Lawn Tennis Association of Australasia was one of the twelve national associations of tennis which established the International Lawn Tennis Federation (ILTF) in a conference in Paris, France on 1 March 1913.
 From 1905 until 1919, New Zealand and Australian tennis players participated in the International Lawn Tennis Challenge (Davis Cup) under the alias of "Team Australasia", the team claimed a title six times (1907, 1908, 1909, 1911, 1914, 1919), however, there were attempts to severance this trans-tasmanian partnership, in order to allow New Zealand players to represent their nation on international tennis events.
 In 1922, New Zealand dropped out from this partnership and on 16 March 1923 New Zealand Lawn Tennis Association was granted affiliation to the International Lawn Tennis Association and thereby became eligible to enter the International Lawn Tennis Challenge in its own right.
 New Zealand Lawn Tennis Association filed its first challenge with United States Lawn Tennis Association for 1924 International Lawn Tennis Challenge.
 Tennis New Zealand was the founding member of Oceania Tennis Federation in 1993.
The Virginia Slims Circuit was a tennis tour consisting of a group of originally nine female professional players.
 Formed in 1970, the Virginia Slims Circuit eventually became the basis for the later named WTA Tour.
 The players, dubbed the "Original 9", rebelled against the United States Lawn Tennis Association (USLTA) due to the wide inequality between the amount of prize money paid to male tennis players and to female tennis players.
