I think both Captain Toad, Hyrule Warriors and Nintendo Land can be considered new IPs - and successful ones at that.
Captain Toad became it's own thing even if it was based on Mario 3D World's bonus stages.
Hyrule Warriors might share game design with the Warriors series, but it's also it's own thing: characters, enemies, items. It just plays like a Warriors game.
Nintendo Land might be a mini game collection based on Nintendo characters, but other than that, those same characters are used in different types of games, with only a few being to already existing games.
