The Hallyburton Johnstone Shield is the premier domestic women's one-day cricket competition in New Zealand.

[1] The tournament began in 1935–36, as a first-class competition, but is now played as a 50-over competition, with six provincial teams taking part: Auckland, Canterbury, Central Districts, Northern Districts, Otago and Wellington.

The tournament began in 1935–36 as the Hallyburton Johnstone Challenge Shield, after the interest generated from England's tour of New Zealand in 1934–35.

In 1983–84, Southern Districts replaced Otago for five seasons, and then afterwards the tournament went back to 5 teams competing.

[2] From 2007–08, the Twenty20 Super Smash began, and games from both tournaments were often played over the same weekend.
