I have just learned a valuable lesson about SEO, hosting a .co.nz domain with Hostgator in USA, is VERY bad for SEO, I need to host it in NZ to have a NZ IP address.  My question is, when I change to a NZ server, will my current SEO 'equity' be lost?  is there a way to tell is all my pages and posts are indexed with the NZ IP address, when this eventually happens?
