New Zealand did not name individual squads for the WODI and WT20I matches, opting instead to name a combined squad of sixteen players for the tour. In August 2021,
Rosemary Mair was ruled out of New Zealand's squad due to an injury.
Molly Penfold was added to the squad as Mair's replacement.
Maia Bouchier and
Charlie Dean earned their maiden call-ups to the England team for the WT20I matches. However, both players were ruled out of the first match after being identified as possible
COVID-19 contacts, with
Emma Lamb being added to England's squad.
Anya Shrubsole was ruled out of England's squad for the first two WODI matches due to an ankle injury. Maia Bouchier was added to the WODI squad ahead of the third match of the series, but was released before the fifth match to enable her to play in the
2021 Rachael Heyhoe Flint Trophy final. ==Tour match==
