I don't see New Zealand comprehensively outplaying SA, SL or OZ in the matches to come (including possible semis, and final). So it seems to me that the only way they can win is through luck - the opposition playing below-par in a number of games, for instance.How would you define "massive amount of luck"? How do you define luck in sport in general?
If NZ can somehow raise their game I think it will be down to Bond and/or Taylor, and possibly Styris. I don't see anyone else performing consistently over the next 4 (possible) matches.
