"You see, the Wii U System Update is not 5GB for a start – it’s more like 1.2GB as confirmed by many who have since watched their internet bandwidth counters tick over while downloading the file. The 5GB confusion comes from the fact that the Wii U Operating System (dubbed by some ‘WiiOS’) takes up around 5GB of memory on the built in hard drive. What this means is even if you don’t run the update, your hard drive will have 5GB used up for the system software.
Further, Mr. Bigshot need not be so impatient in future. The “Day One Update” can be downloaded in the background.
When you first set up your WiFi settings on the Wii U, the console finds an update to download and asks if you wish to continue to download. You then have two options; “Yes” and “Cancel”. Hitting “Cancel” will return you to complete the system settings and will load up the Home Menu as normal, leaving you free to play your games as you wish."
