Young midcourter Kimiora Poi, a key player in New Zealand under-21's win at the World Youth Cup, will make the move south to Christchurch from the Central Pulse.
The Tacix have re-signed a core group of six players: Jess Moulds, Erikana Pedersen, Zoe Walker, Charlotte Elley, Temalisi Fakahokotau and shooter Brooke Leaver.
Shooter Ellie Bird has also earned a contract after stepping up this year from the Tactix's second-tier Beko League team.
