Yes, contacted the hotel about a reservation 2 weeks ago. No response yet and I have had to find alternative accommodation.
Google/Visit Butterfly Creek. There is also a great mini golf close by if you don't have time to go into Auckland.
Other than being close to the airport, I am not sure there is much else to do and see. I stayed on a business trip and most of my visits were in the industrial estates adjoining the airport precinct. The hotel is a high standard as expected from a Novotel and is very handy for that purpose.
Just the airport shops as this fab hotel is literally across the road from the terminals, or catch a shuttlebus or a bus into Auckland city.
