That's interesting, so do quite a few of these lakes not really have an outflow anywhere?

I think so, Rotorua is a crater lake that apparently drains to Rotoiti, but Rotoiti doesn’t seem to drain to anywhere.

I guess you could dig canals to connect all these bodies of water, and then connect that out to sea, but it would be a massive job.

Yup, the one that feeds into Tararua, lake Rotomahana, where the pink and white terraces are buried, doesn't have an outfall. I think an artifical tunnel may have been built, but it doesn't normally have one.
