I can’t add anything to the list, but you’ll have an awesome time. 4yrs ago we went for a month and did 1 week NI, 2 in SI, 1 in NI (my sister, uncle, aunt, cousin all live in Auckland)
We wished we’d spent the month in SI, it was ace – I really enjoyed Queentowns (Fergburgers)
Sadly, now we have a sprog we just go to NI to see my sister now (but I’ll be in Auckland when you’re out there, probably seeing this thread updated with awesome photo’s!)
Don’t forget to go to the bridge and look at idiots like I was
