Air New Zealand operates a weekly flight to Niue from Auckland. Flying from New Zealand you arrive a day earlier because Niue is across the international dateline (Niue and Samoa share the same day). Avoid coming around Christmas when the flights will be full of islanders returning home.
Reconfirm your flight reservations well ahead at Peleni's Travel Agency in Alofi. They can also help with general tourist information and can arrange car rentals and tours.
The freighter Southern Express sails monthly to Tonga and other Pacific countries. The agent is Des Hipa at Ali's Giftware in the Commercial Center, although passengers aren't usually accepted. Large ships must anchor offshore and their cargo is transferred to the wharf by lighters.
Yachts anchor in about 15 meters (good holding) in an open roadstead off Alofi and are well protected from all winds except those from the west. In summer especially, going ashore can be scary when there's a swell. The Niue Island Yacht Club provides 16 secure moorings in Alofi Bay that can be used for NZ$5 a day. Water, toilets, and showers are available at the wharf, but it's necessary to have a bridle arrangement on the dingy to allow it to be lifted out of the water using an electronic winch.
Yachts must call "Niue Radio" on VHF channel 16 for clearance before coming ashore. Customs and immigration share an office just up the hill from the main wharf, but they're normally closed on weekends (exceptions are often made). The airport departure tax also applies to yachties. An annual yacht rally is held around the end of August if enough boats are in the bay. In good weather, Niue makes an excellent stop for yachts sailing between Rarotonga/Aitutaki and Vava'u.
