Blenheim Airport Review is part of the TPOL Down Under Trip Report.
The flight from Blenheim to Auckland is only an hour and a half long. There’s no need to show up to the airport early. I described how great Aussie airports are. This one was even better. The ticketing counter and the departure terminal are in one room. There is no security. Imagine living in a world where this was the norm?
The plane was another prop plane. If you have a choice, sit on the right side for views of the Sounds. 
Thanks for reviews. I plan on going to NZ in October and think I might fly into Blenheim from Auckland and drive around the north part of the south island. Looks lovely.
