Mr Kerr's previous marketing experience included 21 years at Cardrona Alpine Resort, where he worked on brand building and raising the profile of the resort.
He also worked for Queenstown company Good Group, primarily focusing on project, brand and strategy development for the fast-growing company over a five-year period.
Since 2009, Mr Kerr has run his own marketing consultancy business, Synergy in Business, with his clients including some of the region's most high-profile tourism and regional promotion organisations.
Ngai Tahu southern regional general manager David Kennedy said the company was "absolutely delighted" to have Mr Kerr on board.
"Nigel is highly respected and has a huge network of contacts across the Southern Lakes and New Zealand tourism industries, so we're delighted that he's chosen to work with the Ngai Tahu Tourism team."
Mr Kerr said he was looking forward to starting in his new position.
"It would be hard not to be excited about this role, because Ngai Tahu Tourism offers such a diverse range of iconic products and is recognised throughout New Zealand as an industry leader.
"I really enjoy working with the team at Ngai Tahu, because everybody is valued for their contributions to the businesses.
"With such a range of products, there will be a different challenge every day."
