I have a .com.au site ranked 1 on Yahoo.com, 1 on Yahoo.com.au, but nary a mention on Yahoo.co.nz

Why wont Yahoo NZ show this site when they show sites that rank lower on both other Yahoos, have lower Page rankings, no content to speak of and arent as relevant

Can someone offer a solution to getting an Australian site shown on Yahoo NZ, and for that matter, Google NZ. the keywords are all Australian related (people search australia, people finder australia)
