Islands by Wikipedia Descriptions

Some people call Mauritius the Island of Space Cowboys.

What a Joker.

The casinos of Macau are on a connected island, although the name of that is not Macau. And you're right, in Montreal the name of the main island is Montreal.

I read the question as what place has flights TO those cities, just saying.

Last time I checked, all three of the cities mentioned are on the South island.

I don't quite get you problem, the flights are going from outside (probably mostly Australia) TO the airports on South island. Why should they increase tourism on let's say North island? Or the other way around, why should flights to Auckland and Wellington increase tourism to South island?

The clue uses the term “the boroughs”, implying that they are famous boroughs. I don’t think any other set of boroughs are so well known. Also, as a counter to the American-centric argument, if it were asking for a country whose regions are composed of cantons, it’s fair to expect people to answer Switzerland even though cantons exist in other places too, right? It’s just that they’re most well known in Switzerland.

In my old children's encyclopaedia and other books way back in the 80s, Australia was the world's biggest island. Then somewhere along the line it got de-islanded on the "logic" that no continent is an island. A bit like Pluto.

I'm sure there's a quiz waiting to be made about this stuff

There's no official scientific delineation between "island" and "continent," or indeed what "continent" is, exactly. The distinction is entirely cultural. Some places consider Australia an island, some places say it's a continent, some say it's both. The US generally goes with Australia not being an island, and that's the standard on Jetpunk. Without Australia, Greenland is the world's largest island, and New Guinea is second.
