Yeah, for Pool A, I'd say that Nz v Australia is always worth a watch, in any sport - even though Aus really shouldn't trouble NZ in the slightest. Wales and Scotland are fairly evenly matches; but there won't be much interest in NZ, and we get to see them play each other every year in the 6N - which would be okay of they're playing to top the pool... but as is, they're both likely playing to avoid a white-wash.
Pool B is a real group of death, with nothing in it between Canada, USA and Italy - however, none of those match-ups is likely to get the local public particularly stoked.
Pool C has got England v France, which, like NZ v Aus is always worth a watch; but should be a stiffer test for the favourites, but Eng would still be heavy favourites - I'm sure this would get far more viewers if played in Europe.
TBH, and sorry for this, it's a problem for women's rugby at the moment anyway; exaccerbated by playing in NZ - where I don't think the populace will turn out to watch anyone but NZ, even the final if NZ somehow fail to make it there.
Women's rugby in England has been getting crowds well North of 10k this year, and they'd probably get close to filling twickers if England were involved in a RWC final (albeit with relatively cheap tickets); and I suspect you'd see crowds of 10k turn out in England for NZ, France, Wales and Scotland playing, and probably get close for USA & Canada too.
The crowds aren't there yet elsewhere, and nor is professionalism TBH (am I right in thinking England are the only team who've been actually professional for more than a year? certainly the only professional league).
