For as long as the Earth revolves around the sun, I believe, New Zealanders and Australians will never be comfortable with the American cancer of tipping people just for doing their jobs.
In the cruise industry, the practice is entrenched, but for the most part, you at least know in advance what you're in for.
On my recent cruise aboard the Celebrity Solstice, stateroom accounts were automatically levied at US$12 ($14) a person a day (that's US$336 a couple for a 14-day cruise) to tip the steward who cleans your cabin and the waiter and drinks stewards assigned to your table in the formal restaurant.
If you prefer to tip them directly, or not at all, it's possible to opt out of this system by telling the guest relations desk not to add the levy to your bill.
