FWIW I got this from Mike Lee who does the package trips from when I was going to go over in July:
I would take a 10 and a 14m wind is usually around 15 to 20 knots I have boards if you need it
flying air new Zealand and air raro is 23kg
bring your repair kit for bladder and canopy should be OK
Looking at wind finder for this week his 15-20 knots average looks about right.
