Hi Greenlfc 
I'd be looking at something like a pfsense box as my edge device and a ubiquiti unifi AC-PRO for your wireless.  Depends a little bit on your skill level.
  I did a search for both of them, pfsense box firewall on amazon.com, and a site for ubiquiti unifi AC-PRO 
  for my wireless   in New Zealand looks fine but would it work with ultra fibre and spark New zealand and 
  my skill level not that good, perhaps the link in new zealand per ubiquiti unifi AC-PRO for my wireless
  might helps me set it up, I think about it and thank you for the suggestion.
