Six Senses has confirmed that its management agreement for the Six Senses Sanctuary resort in Phuket, Thailand will terminate on 31 July 2011.

The resort, on the island of Naka Yai in Phuket, is owned by Thai property company Erawan, which has 13 three to five-star hotel and resort properties in South-East Asia.

A spokesperson for Six Senses, told Spa Opportunities: "Six Senses Resorts & Spas and the owner of Six Senses Sanctuary in Phuket have ended the management agreement relating to Six Senses Sanctuary."

The resort will close for redevelopment work and refurbishment on 1 August and will reopen on 30 September with a new operating company which is yet to be announced.

Erawan has strong relationships with US-based hotel giant Marriott and French hotel group Accor. All its other hotels and resorts are operated by these two groups.

The change leaves Six Senses with three Soneva resorts, four Evason properties and seven Six Senses resorts, along with 20 other city, hotel, airport and on-board spas and resorts in Asia, the Middle East and Europe.
