As an aside, a lot of discussion has taken place over the last few years about the branding of the men's sevens team as the "All Blacks Sevens" team. At the time the decision to give them and the NZ Maori team the name "All Blacks" was taken, there was no mention at all about what would happen to the women's teams. I interpreted that as a sign that they didn't see the women's teams as teams that they considered useful for their marketing of the brand "All Blacks" but also that they didn't consider "Black Ferns" as a brand to be marketed.
Things seem to have changed. The "Black Ferns" seem to be becoming a brand of its own, as in the last few articles (basically since Rio), the NZR publications are referring to the women's sevens team as the "Black Ferns Sevens" (they didn't do that before Rio). Whatever you think of extending the XV's names - as brand names - to other teams (I'm not posting this to re-open that discussion), I think it's a good thing that they're now also looking at the women's teams and that they are apparently considered as something that's "brand worthy" (even if not to the same degree as the ABs).
I can only assume this has something to do with the women's silver success at the Olympics and the upcoming Women's Rugby World Cup in 2017.
