The New Zealand based branch of the agency will work with the NZOC on their entire communications strategy, beginning with campaigns to support its Winter Olympic team at Pyeongchang 2018.

Attention will then turn to the New Zealand Commonwealth Games team, who will be competing in Gold Coast in April 2018.

The deal will also see Saatchi & Saatchi remain on board through to the 2020 Olympic Games in Tokyo.

"We were really impressed with the work we saw from Saatchi & Saatchi and the way they approached our challenging brief," said Sharon van Gulik, NZOC's commercial director.

"They presented compelling creative strategy and ideas that we are confident will resonate with our team members and their fans and supporters throughout New Zealand and the world.

"We are looking forward to a great partnership in the months and years ahead."

Van Gulik also commented that Paul Wilson, managing director of Saatchi & Saatchi, and Toby Talbot, chief creative officer, as well as the whole Saatchi team "felt like an excellent cultural fit with us which was also key."

The global communications and advertising agency has a network of 140 offices in 76 countries and employs more than 6,500 staff.

It was founded in London in 1970 but is now based in New York City.

"It's an honour to be working with such a prestigious and inspiring organisation as the NZOC," added Wilson.

"Sharon and her team have an exciting vision for the brand here in New Zealand and we are delighted to be able to support them in achieving it."
