It's because the tramway here is dual guage. The Auckland and Australian (Melbourne) trams are wider than the other trams, so they use the outer rails, and the narrower trams from Wellington use the inner rail. I'm glad that there is only two sizes otherwise it'd be a lot more complicated! As you can imagine, this causes a problem at the points, and is possibly a video I could make in the future.

Why need three tracks under the tram?
