That seems reallllly fishy... Nintendo Land is one of the oldest games. If it's asking you to update, it has to be a re-print. Out of curiosity, what is the code on the case and disc? See ja450n's post above yours for an example of what the numbers should look like (or below).
My Nintendo Land (came with SM3DW bundle in Dec 2014):
Case: WUP P ALCE USZ 78974A Made in USA
Disc: WUP-P-ALCE-USA-0 Model No. WUP-006 (USA)
Not sure if this has been resolved or not. I just got a Nintendo refurb Zelda bundle, disc code is the same as yours, but it's also prompting me for a system update when I try to play off the disc. I can't seem to find the rest of the Case code, only see WUP P ALCE USZ, then below is TBA-WUP-ALCE-USZ-CO
