Matakana village, a few minutes away by car, had plenty to keep Margaret distracted, and there were also ample diversions for their children and grandchildren - loads of room on the property for a game of footy, a river and pond to potter around in, and a choice of family and surf beaches within striking distance.
A large, near-level site, meant Kerry and Margaret didn't need to compromise on the orientation. They worked with now-retired architect Norm Kirkcaldy to design a single-storey, north-facing three-bedroom home that soaks up sun and opens out on to terraces and a flat lawn.
In the years that followed, Kerry and Margaret planted more than 200 native and exotic trees, replaced half the lawn and added a large concrete patio, accessible through bifold doors from the open-plan living area. With an outdoor wood fire, a shady umbrella and lighting, it's a wonderful spot day or night, summer or winter, says Kerry.
"It's another living area. At night we light the fire and have long enjoyable evenings out there."
Kerry was keen for the home to sit comfortably in its surroundings, so they incorporated natural touches into the design including macrocarpa ceilings and Waipu stone features inside and out.
"I wanted it to look like a country house. I didn't want it to be a modern place that didn't fit into the environment - I wanted it to reflect that environment."
In the 14 years since they bought the property, the vibe of the district has tilted in Margaret's favour, as the former sleepy hollow of Matakana transformed into a buzzing village in the weekends, alive with cafes, restaurants, boutique shops and a cinema, and farmers' market.
But though the area has become increasingly popular as both a commuter suburb and weekend getaway for Aucklanders, it's maintained enough of a laid-back rural feel to keep Kerry happy.
Their grandchildren are now getting older and busier - and two of them live in Australia - so Kerry and Margaret have been spending more weekends in Auckland or Sydney rather than Matakana.
Kerry says the house has served them well, and they'll be sad to leave. "It's been a refuge for us, and I need that. I work pretty hard during the week so it's been outstanding to be able to go there. It's a wonderful place."
