Thanks, now it's working. I don't use it often and the last time I did it just worked. 

I just search from the Chrome address bar using

site:geekzone.co.nz (search query)

 Its not working for me here, im a subscriber, but i have also disabled my ad blockers on geekzone

Check everything else that could block Google - script blockers, Ghostery, etc. We don't serve the ad codes to subscribers (if they have the option to browse without ads checked) but the Google Search is a script that we have to server and some ad blockers will intercept it.
