The White Ferns will host ODI and T20 world champions England and Australia over the second half of this summer.
The England women's side will arrive in New Zealand on January 26 and undergo the mandatory 14-day managed isolation period ahead of playing the White Ferns in three ODIs and three T20s between February 23 and March 7.
Less than a week after England depart, the Australia women's side will arrive in the country and undergo managed isolation ahead of three T20s at Hamilton's Seddon Park and three Rose Bowl ODIs at Mt Maunganui's Bay Oval.
England are the reigning ODI world champions after beating India in the World Cup final at Lord's in 2017 while Australia women hold the mantle as T20 world champions after defeating India in the final of the T20 World Cup in Melbourne last year.
Four of the T20s (three against England and one against Australia) will be double-headers alongside Black Caps fixtures, and two ODIs (both against England) will be part of "back-to-back" events in which the White Ferns will play at the same venue, the day after the Black Caps.
NZC chief executive David White said he was delighted to be able to confirm the two tours at a time when women's international cricket had ground to a standstill around the world.
