Ms Walker said Crowne Plaza Queenstown was an ''iconic property'' and she considered herself fortunate to be joining ''a fabulous team which is committed to its success''.
Ms Ellerton has been promoted to the role of Crowne meetings director as part of the hotel's commitment to supporting staff to ''move through the ranks''.
In 1997, Ms Ellerton started her tourism career with Swallow International Hotel Group in the United Kingdom and joined the Crowne Plaza Queenstown 10 years later as a food and beverage attendant.
She worked her way up to restaurant supervisor before moving into the banquets team.
