You can stream Justice League from Canada on Netflix, but it’s not available in New Zealand or India. Netflix detects your location by looking at your IP address and blocks content that isn’t available to you — this is called geoblocking. While a VPN can technically give you a new IP, and hypothetically let you watch Justice League from anywhere, this goes against Netflix’s T&Cs. Plus, it could be considered copyright infringement. However, if you are located in the UK or Canada and want to stream Justice League safely in HD, I recommend ExpressVPN.
