I visited Pakatoa island for a few days on the long weekend! The caretakers, Nigel and Fi, have a microwave link to Waiheke island, but are otherwise completely alone.
It used to be a resort in the '80s, and everything was basically abandoned as-is. The cabins still have tables set and beds made. In the background are a bunch of Wekas; free of introduced pests, they've basically taken over the island.
Their house is basically 2 cabins on the beachfront, with the dividing wall knocked out. Across the road is a pub and restaurant. There was a lot of original food and booze left sitting around (the tuckshop is still set up with a till and a bunch of stock, and the bar is fully stocked with circa-80s beer/wine/spirits).
We went diving for scallops in the morning. You just see the mast of his (24ft iirc) sailboat on the left; Nigel is planning to do a solo trans-tasman crossing next year.
There used to be a power cable to the island connected to a substation, but it keeps getting picked up by anchors and dredges. Nowadays there is wind, solar, a big new generator, and an older generator.

"Harrods", the old rubbish dump. All the good stuff has been gradually dug out and sorted.
The dam, used as a backup water supply and to irrigate the golf course (once a planned use for the island).
The main beach. Mistake Not is moored in the background.
