It is a bit tough to say as their are some big differences between the two. If money was not an issue, I would chose Matakauri because my experience at Cape Kidnappers was so wonderful and they are owned by the same family. I would say the decor of Matakauri I preferred over Azur, but I did think Azur was lovely.

I will do a quick summary between the two of biggest differences.

Matakauri
-higher cost (2-3 times the price of Azur)
-15 minutes to town
-one room is 32 square meters, others start at 72 square meters
-main lodge is bigger
-Virtuoso member and comes with amenities as such

Azur
-complimentary (and unlimited) transfers into town
-5 min to town
-in a residential neighborhood
-evening meal not included
-all rooms identical and 75 square meters

Both have lake and mountain views, breakfast, pre-dinner drinks with canapes and strive for privacy and luxury for their guests.

Even though I saw the properties back to back, I did feel a bit closed in at Matakauri, which probably isn't fair as it was weather related. I think it is because Matakauri is up against the lake with trees surrounding the property and Azur is further back. It was raining, as you can see from the pictures, and we didn't have great views.

I hope that helps. I will PM you with some other info on the area. Four nights would be a nice stay as you can really see the area well then. And yes, we were a bit full on and really, really had a good time!!
