I don\’t normally plug other sites, but this one looks like a good one for businesses in NZ – www.madefromnewzealand.com
My biggest like is the tone it seems to have of a great place to be; lots going on, plenty of information on businesses, people and events.
The other cool aspect is the social side of things.
Not only is the site itself a social networking experience, they have also made the effort to integrate the site into other social networks. You can link to your Facebook profile using Facebook Connect, you can also attach your blog to your profile and use RSS to bring in your latest posts.
A possible suggestion is to something similar to Twellow, where they offer integrations to a larger range of other networks including Twitter, Flickr and more.
They even have blog plugins to provide an easy way to share people, businesses and networks with others via the blog. Here is one to my profile: [business:Deepweb]
So a great place to get listed and connected with other businesses in NZ.
Give it a go.
