There is no tipping in the South Pacific, including cities on the "big islands" of Australia and New Zealand.
For the island groups, the first time you arrive, you're an honored guest, and the second time you are family; neither would tip.
Many resorts now have so-called Christmas fund jars up front where you can give a few dollars daily (the money is divvied up among the staff).
Subtle exceptions to the no-tipping norms include a restaurant that blows you away with service and food; tip 20%.
In many resort restaurants, a 10% tip may be included, but you don't have to add to it.
Porters in hotels may receive a few dollars for carrying your bags, but they usually do not expect it.
For the cleaning staff, tip a few dollars and do it face-to-face or leave it with the front desk in an envelope at trip's end.
Concierges -- if they do something really special for you at a five- or six-star resort, tip accordingly.
Some top resorts have butlers, whom you should tip $5-10/day.
Spa treatments, winery visits, group tours are other instances where you may tip up to 15%.
Always tip in local currency, not in U.S. dollars.
