Clothing list -- what else do I need?

Our NZ hike (december) is coming up, we are just finalising our gear lists and in particular doing our final clothing shopping on the weekend.
This is my list so far, mostly I have raided my sailing wardrobe. We have some money to buy a few extra bits of gear, I would love some advice about where it would be best spent (if at all).
feet
Boots
Socks (Merino x 5pair)
bottom
Shorts (70%cotton/30%nylon - not optimal, but everything else I own is 100% cotton)
3/4 pants (50% cotton/ 50% nylon)
top
wicking layer (92%nylon/8%spandex - it is one of those shirts you wear while swimming -- will this work?)
Short-sleeve shirt (100%polyester - thomas cook 'amphibian' shirt)
light-weight long-sleeve shirt (100% polyester - feathertop)
heavier long-sleeve shirt (100% polyester - feathertop)
outer
vest (100% polyester - feathertop)
Wind-jacket (polyester, spandex, nylon - feathertop)
Gore-tex jacket

Things I want to buy
