If it's a standard fibre install you should be able to plug your new router straight into the ONT and you will be good to go, shouldn't need the netcom unit. Just have to make sure you tag the WAN traffic as VLan 10. Most routers in NZ have this option in the firmware so it works with the fibre network. Same for all the providers, ie chorus and the other UFCs, in my case UFF. Sent from my Pixel 6 using Tapatalk
