This would be amazing for anyone heading out to the bays or Wellington Airport, no intersections or lights to worry about, and it would make life so much easier for the CBD as well, not having so much through traffic in the CBD.

You're forgetting Karori, and that's just vehicle tunnels. There's also the many train tunnels around Wellington.

I realised there's the cable car too, although that's a funny great area.

Certainly the prospect of building a tunnel under the guts of the city for several km (where it's likely to cross a fault line) is edging towards this kind of nightmare: https://blogs.agu.org/landslideblog/files/2011/03/10_10-Canterbury-22.jpg

I can't see how a tunnel would sustain that, which seems like a death knell for the whole idea...

It's certainly been done, it's not an insurmountable obstacle.
