That's more of an English law thing. Doesn't really happen in NZ.
Hmm..ok, I need to do more research then.
See my comment below - I don't actually know much about the NZ law, which is proof that it doesn't come up very often as I worked in land law there for 2 years (and had one case of adverse possession all that time, but it wasn't govt land). Have worked in land law in the UK for 2 months now and it is a very common issue!
I've never heard of anything like that.
Google "adverse possession"
Working for a council it's something we come across all the time, as we own so much land we can't be constantly checking on it. So for example, if someone's been mowing the grass verge in front of their property for years, they can then claim they own it. Of course, when it's not a grass verge but a flat or larger piece of property that's fallen through the cracks at some stage it can pose a big problem.
In NZ there is still a doctrine of adverse possession but it's not nearly as wide as in the UK.
