We are cycling the Queen Charlotte track at the end of April and need to transfer from Picton to Blenheim Airport on the afternoon of 30 April to catch a 4.50 pm flight to Auckland. If possible, I would like to cycle the last part of the track from Lochmara to Anawika and then on to Picton on the 30th of April and still make it to Blenheim in time. There is a bus at $10 per person that leaves at 12.30pm for Blenheim, but I am looking for a later departure time. Private transfers costs $60, as well as car hire. Are there any other reasonably priced means of transport between Picton and Blenheim airport that departs between 2.00pm and 3.30 pm?
