I'm talking about modern times. Owned land is stolen land.

I don't know enough about Māori to say much about their land management practices prior to colonization. But I know Māori have nobility so it's entirely possible and perhaps likely that it was stolen from other Māori.

Who ever was there before them.

Yep, it's akin to a "all property is theft" take on things.
I bought my shoes, i didn't steal them. I bought the cheese in my fridge, I didn't steal it Hell, I even bought the fridge.

And, yes, I bought my house and garden. No stealing involved... unfortunately. Because it was fucking expensive, but, alas, I was not allowed to steal it.
Someone may have 'stole' it by staking a claim to it a few hundred or possibly over a thousand years ago, but my hands and conscience are clean (about the land, at least).

No one still has yet to steal the Sentinelese’s island.
