Hello Kate and Hellen,
We are quite interested in this,
I think we will arrive in Auckland about Dec 10,
And we need 10 days to apply for IRD as I dont have driving license 
so the earliest we could arrive Te Nikau Retreat is Dec 22,
We shall double cfm this when we arrive in NZ,
And we shall have 3-4 person then,
Is that okay?
I see Te Nikau Retreat lie in south land?
is it near Nelson or Christchurch?
Thanks!
Viki
