As for a search engine, look elsewhere I would recommend looking elsewhere. Check out Teoma, or WiseNut, or Gigablast. That is, if you are looking for a 'real search engine' with an algorithm, results, and the whole bit. As far as I know, Engine54 (formerly 'bestoftheweb' for all you history buffs) has never run a spider and utilized an algorithm to classify unstructured hypertextual data from the web. :)
If you want a pay for spidering engine like Altavista or Inktomi [webmasterworld.com], or pay per click search engine [webmasterworld.com], check out those two forums.
Just as an FYI, this forum is generally intended to be used to discuss search engines, which is why I pointed to the other forums, in case you would like to discuss engines which are mostly bought and paid for results providers.
As to your question, though: any good? Well, my opinion is that if I'm shopping I'll use Overture (to browse, don't recall actually buying from a site I found through their service) and if I want info, I'll use Google, then Wisenut, and then Teoma.
Also, try the site search link at the top of each page...there are a few New Zealand threads out there.
