For NZ$130ish you can help sail one of two former America's Cup yachts around Auckland Harbour for a couple of hours with SailNZ.
It is well worth the money, particularly if there is a decent breeze which will show you the kind of speeds the boats are capable of and give you a taste of the thrill of America's Cup racing. You can help work the grinders and even take the helm.
It's also a good way of seeing the harbour and getting a water-side view of the city. More than anything, I found this a rare highlight in an otherwise dull and disappointing city.
