TVNZ has Chromecast support available in our latest iOS and Android app versions. In order to use Chromecast with the app, please make sure you've updated to the latest version.
If you'd like to cast to Chromecast from your PC/Laptop, all you have to do is Cast a Chrome browser tab to Chromecast, mirroring what’s on your screen on the TV. For the best experience, please try to have the latest version of Chrome.
You should be able to see a little Cast icon in the top right of your browser window, just to the right of the URL bar. Simply press that icon in the tab you want to Cast, choose the Chromecast device you want to Cast to, and the icon will turn blue.
