Do you need to finish the game in order to get Liberty Pass?

Question

I heard that B/W tooks longer to finish than older games, and my Wi-Fi is working randomly...

Answer 1

No you just need to get the basic Pokedex like in every game where you get an event pokemon.

You may even be able to get it BEFORE you start your game. The Mystery Gift option is right there in the menu before you start your game.
