"That's because this isn't my territory. I'm walking into someone else's [territory] so that's why it's so different for me.

Tuivaiti has been forging a combination with "old head" Te Amo Amaru-Tibble although Tiana Metuarau, who only turned 16 this month, comes in at the other end of the spectrum to provide balance.
■ 2017 Pulse squad: Te Amo Amaru-Tibble, Sara Bayman, Sheridan Bignall, Karin Burger, Ameliaranne Ekenasio, Katrina Grant, Phoenix Karaka, Claire Kersten, Whitney Souness, Cathrine Tuivaiti.
