Wilfred and Norma Nuttall are 92 and 90 years old respectively. They have been married for more than 70 years and have lived in the same Napier house for 66 years.
Wilfred founded Napier-based welding distributor Weldwell, after honing his welding skills on New Zealand Air Force planes during WWII.
These days, Weldwell is part of American Fortune 200 company Illinois Tool Works.
"Their house is exactly the same as it was when I was a kid," said Mr Nuttall, remembering trips to Hawke's Bay from Wellington as a child.
The reunion also drew Mr Nuttall's sister and her three children from Connecticut in the US, as well as family from Wellington and Australia.
The Nuttalls, 28 of them in total, including three of Wilfred and Norma's children, 12 grand children and 6 great-grandchildren, enjoyed Christmas dinner together at Cape Kidnappers last week.
They've also been on a whirlwind tour of the region during the past few days, trying their hand at golfing, claybird shooting, and even kiwi-spotting.
"[Wilfred and Norma] did extraordinarily well, given they're not used to all this activity."
