Jet Boating
Jet boating sounds like a fun activity and it sounds really fun to do. It is a lot of money but it seems worth it. For an adult the cost to go jet boating is $81.04. Jet boating was kinda "made" in New Zealand so that is probably the best place to go jet boating. One jet boat can hold 23 people in it. It is open from 9 AM- 5 PM. These trips will take you under the harbor bridge and exploring the harbor.
Sky Walking
After Jet Boating why not go sky walking? For an adult it coast $119.90. You take a walk on the famous SkyTower to get an amazing view of The beautiful harbor and Auckland greatest landmasses. You experience the sensations of being 1.2m outside the observation deck walkway. There is nothing on either side of you but don't worry you are completely safe. You are in a full body harness and over head safety lines. Sky Walking is open from 10 AM to 6 PM. Oh and remember booking is recommended.
