Important: Please do not power off your Wii U Console during the System Update.
The length of time it takes to perform a system update varies depending on the speed of the Internet connection used. Please be patient.
Due to the amount of new features and applications included, the system update may take an extended amount of time when performed during the initial setup (for some users it could take an hour or more to download and install). Do not power off your Wii U console during this time.
Should you experience any issues completing a System Update please contact Nintendo Customer Service Monday to Friday, 9:00am to 5:00pm Australian Eastern standard time on: 03 9730 9822 or New Zealand customers please call: 0800 743 056 so that we may provide you with further assistance.
