President of the NZ Olympic Committee Mike Stanley said he was delighted to appoint Nicol to the role.
"It is my great pleasure to welcome and congratulate Nicki on being appointed CEO and Secretary General of the New Zealand Olympic and Commonwealth Games Committee.
"Nicki has had an outstanding career in New Zealand and overseas in multiple roles, most recently with New Zealand Rugby where she has been a highly respected member of the senior executive team.
"Nicki impressed with her diverse and highly successful commercial background, her proven leadership qualities and her strategic insights. She has a deep passion for sport and respect for the Olympic movement and Commonwealth Games, and what they mean to New Zealanders and to our athletes.
Nicol says she is excited about the opportunity this role presents.
"This unique and special role will draw on a blend of my professional and personal life experiences. The New Zealand team has a fabulous reputation for its performances and successes and how it represents New Zealand. I look forward to working with the NZOC team to support New Zealand's athletes to reach their potential."
Like many New Zealanders, Nicol says the Olympic and Commonwealth Games have made their impression on her.
"I recall Barbara Kendall's gold medal ceremony in Barcelona where I was a combi-van tourist on my OE, waving the kiwi flag with pride, along with a very special afternoon on the Gold Coast when the NZ men's and women's rugby sevens teams took home double gold, as being incredible moments for me."
Nicol will transition into the leadership of the NZOC in March 2022.
