Renowned XDA developer, Chainfire has shared a rooting method for new Google Nexus 9 tablet using the latest SuperSU v2.18.

While the root process is an easy version, it took a few hours for the developer because of the first firmware on the new Android version as well as the 64-bit. The developer is yet to update CF-Auto-Root framework to patch the kernels live on Android 5.0 or support 64-bit.
