Later, as we emerged from lush pohutukawa groves and native bush, Barbara was waiting with a hot cuppa and a ride back to town.
We relaxed that evening with dinner at Pepper Tree Restaurant, where we warmed up by the open fire and enjoyed fine local cuisine served by cheerful, helpful staff.
Back at our accommodation, The Anchor Lodge Resort, Jack still had more than enough energy to sit up and watch the All Black test while I dozed. We stayed in a separate, self-contained apartment in a treetop setting, which even in deepest winter was toasty and comfortable.
First stop on Sunday was The Waterworks, a quirky adventure playground showcasing Kiwi ingenuity at its best, including moving, interactive water sculptures. Jack loved the human hamster wheel, water cannons and flying foxes; both of us were fascinated by the giant water-powered clock and we vied for first place in the mini-boat races where we are told cheating is compulsory. There are barbecue and picnic areas, and a cafe, so it's easy to spend all day here.
Just north of Coromandel town is the Driving Creek Railway, lovingly built by local artist and railway enthusiast Barry Brickell. The one-hour round trip in one of the specially built passenger trains leads to the Eyefull Tower, which sits 165m above sea level and offers stunning views over valleys of native bush to the Hauraki Gulf.
Don't miss the Gold Stamper Battery, a gold processing plant, where geologist Ashley Franklyn exuberantly shares his passion of the extraction process and had Jack intrigued at the prospect of finding gold in nearby hills.
It was a fitting end to a weekend that was like stepping back in time. You leave hoping Coromandel town won't change, and that its waitresses will continue to hand-deliver dinners to locals as part of the service.
