The council said this was "re-shaped based on the calibre of candidate, on the recommendation of Sheffield, our independent recruitment firm and to align with the likes of [similar economic development agencies]".
Ward holds an MSc in cellular biology and molecular genetics from Auckland University and an MBA from Deakin University in Melbourne. His experience includes chief executive roles with the Wellington-based New Zealand Veterinary Association and Crop and Food Research.
He has been involved in research and development, high level partnerships and financial and business performance improvement.
Ward plans to relocate to Whanganui from Levin and says he is delighted to have been selected to lead the team at Whanganui & Partners.
Whanganui & Partners board chair Myles Fothergill said Ward would bring a fresh perspective.
"We certainly had a number of very talented applicants for this position, so it wasn't an easy decision, but we needed the right fit for economic development," Fothergill said.
"We have an excellent, well-rounded team and this is now completed with the appointment of Mark as chief executive."
