Today on NZ Sport History we talk about a moment five years in the making. The Black Ferns Sevens turned around their devastation of losing against Australia and missing out on a gold medal at the 2016 Rio Olympics to triumph at the Tokyo Olympics.
Veteran sports broadcaster Rikki Swannell has written all about the team's journey in her new book, "Sevens Sisters: How a people-first culture turned silver into gold," which goes on sale today.
