Auckland is on the North Island of New Zealand, and the Airport is 13 miles, or 40 minutes south of city center. A bus will take you to city center... and will let you off at various stops if you'll tell the driver in advance. This city warrants more than just a one-night stop.
Walks: The City Council's Parks and Recreation Department sponsors some interesting guided walks around the city... free. Check Tourist Bureau for their "Come Strolling with Us" booklets.
City bus tours: A 1/2 day city tour is recommended. These guided tours take you to Cornwall Park, One Tree Hill Domain, Waitakere Scenic Drive, the ridge lookout overlooking Waitemata and Manukau Harbors, the Museum of Transport and Technology and the Kiwi House.
Ferry rides: Another excellent way to see Auckland is from the deck of a harbor ferry. Catch the ferry at Queen's Wharf on Quay Street. This takes you to the lovely, charming village of Devonport. The ferries depart about every 40 minutes and the trip takes 15 minutes.
Inner Harbor Cruise: These tours last from 1 1/2 to 3 hours and head upstream under the Harbor Bridge to Devonport, the North Shore, Hauraki Gulf, the Bay Islands, and the shoreline of Maraetai, returning via the inner harbor. The shorter cruise departs at 10 AM, 12:15 PM, the longer cruise at 2:30 PM. (Note: New Zealanders own more boats than autos).
War Memorial Museum: This museum houses the finest Maori collection in the world. Pick up a free guide-map in the museum shop. Hours 10-5. To reach the museum, take the Remuera or Meadowbank bus from the bus terminal. A good museum.
Auckland City Art Museum: The permanent collection ranges from old masters to contemporary European art to Japanese prints and drawings. That's what the guidebooks say. In reality, it's a very poor gallery. Hours M-Thu 10-4:30, Fri 10-8:30, Sat/Sun 1-5:30. Located on Kitchener Street beside Albert Park.
Museum of Transport and Technology: The exhibits here include horse-drawn tramcars, steam trams, various locomotives and the world's 2nd airplane. Hours 9-5. Take the 045 bus from Customs Street West. The museum is located on Great North Road and Western Springs.
Parnell Village: This is a restored colonial area containing 100 shops, galleries, and restaurants. A lovely area to walk around and relax and to take pictures.
Bay of Islands: Must take a bus... or Harbor cruise. European culture entered New Zealand here, along with Captain Cook. Today, it's a seaside resort.
One Tree Hill: This hill can be seen from any point in Auckland. There's only a single tree on it, and a 70-foot obelisk honoring John Campbell, father of the city.
