Are the pepper crabs Sat or Sun night? Or Friday?

Why I ask is that flights from NZ arrive mid/late afternoon but the return is the evening so I need to get it right before making any bookings. OTOH I may try to fit in with trip elsewhere as a stopover on the way over/back. Being towards the end of school holidays and the busiest tourist season down here I wont leave it so late planning this time.

PS I have left mike a message about this thread.
