He wasn't sure when Wairoa District Council economic development officer Roz Thomas contacted him, but he had no hesitation in accepting, and didn't come for "a fee."
But there were rewards, he said, in helping others.
"Setting up a business week for four days shows quite a lot of aspiration. It's a healthy starting point," he said after his "Big Picture" address.
"This clearly is an area where there have been challenges. But the people here can accept challenges, and have opportunities."
Among the opportunities were the natural gifts of the region - a "beautiful ocean-front, a beautiful river, and a beautiful lake ... all within 40 minutes".
He could think of no other place with such a combination and discussing the broader "values" of the area, he said "the answer is collaboration".
While the week ended in a wave of enthusiasm, a task now falls on the council and staff to advance ideas.
Ms Thomas, who found Mr Weldon's input "inspiring" with a message of "taking risks and giving it a go", said some steps could be taken quickly, particularly communication aspects and exposing Wairoa, its events and attractions, through websites and other means.
"It's been a successful week."
