You will be able to add points until 2018/03/27 and will be able to buy Wii Ware and Virtual Console games until 2019/01/31.
This also affects the backwards-compatible one on WiiU.
Edit: Redownload of already bought software, as well as the Wii -> WiiU data transfer will stay online for the time being but will also shut down at an undetermined date in the future.
