Jazzgirl, commenters on 225 have observed that Pangakupu tends to include a Maori word in his grids.
Brendan, I've likely been "primed" by having read a number of recent articles about the pay of female athletes, not just in football but cycling.
Being determined to look for that theme, I can posit clues 5, 14a, 25, 27, 22, 12, 4 and (more tenuously) 9 in that connex(ct)ion.
It's not convincing enough to be a theme, though. In particular, nothing specifically "female"! And I strongly doubt "low wages" in general.
