From where I'm sitting, I can see;

cbdfree (WCC I believe)
nzwireless Free WiFi (Waterfront)
Free Public WiFi (Trademe or the Windows SSID honeypot bug?)
nzwireless Premium WiFi

I've been unable to verify what the actual name is of TradeMe's network anywhere. Maybe my Google-Fu is weak but I can't find anything saying "This is it!" - logic would dictate it would have "TradeMe" in the name but I've not come across anything yet.
