In doing the post on timetables (above) I noted air2there have increased their services between Blenheim and Wellington to three a day (only 2 on Saturday) though with one of the southbound flights going via Paraparaumu. They have also added a second flight between Paraparaumu and Nelson each Friday.
air2there's Cessna Grand Caravan ZK-MYH at Nelson on 17 April 2009. I had just flown on it from Paraparaumu.... a great trip. Photo : S Lowe
