If you look at the different types of reserves—and I'll give you an example in a moment of what this means—I found in a quick search scenic reserves, historic reserves, scientific reserves, recreational reserves, and I also found hospital reserves, because it turns out that at some point back in the 1800s, when a local town said, "We need a hospital.", the Government passed a law to say, "Here's some land which we reserve for the hospital." Now, of course, we've got much more efficient planning instruments than that, like the Resource Management Act—I'm joking! But at least we don't need specific Acts of Parliament any more to designate land or give planning permission for land to be used.
