Any Android box can be loaded for overseas TV channels and it is not difficult to do but it may take some fiddling. You also need to be wary of shady IPTV sites if you want to stay on the side of the good guys. You may need a DNS proxy or VPN to circumvent geo-blocking (not to be confused with piracy). Try visiting the sites you want to stream to see if you can download their apps. Then try Google Play. Then search for other providers of APKs, like APKpure and APKmirror. Some will work. Many will not. As has been pointed out, most of these are designed for phones. They can be made to work with varying degrees of success, but navigation is sometimes a pain. A good app to start with is something that lets you rotate the view and lock it, since many phone apps will assume your device is vertical. To sideload, copy the APK to a flash drive and plug it into your box. Then navigate to it with File Explorer or whatever file manager is on your device and click on it to install. Kodi is well worth having. There are many easy to use add-ons for different streaming sites. Avoid the illegal ones. If nothing else, they are often unreliable. You can also use @Apsattv's IPTV playlist for NZ Freeview channels and even Australian ones if you have a proxy. Many people here use DNS4ME. An air mouse with keyboard can also be useful for navigating some apps.
