Visit Britain's four-strong business tourism team is currently facing redundancy as part of cost-cutting measures, now under consultation.
Rodrigues' reappointment will see him promoting Britain as a destination during events including the royal wedding, the Queen’s Diamond Jubilee and the 2012 Olympic and Paralympic Games.
The news comes as prime minister David Cameron announced that the tourism industry has responded "magnificently" to the challenge of creating a public-private partnership to fund a global marketing campaign.
British Airways, DFDS Seaways, lastminute.com, P&O and Radisson Edwardian are the first companies to contribute to the campaign which aims to build a £100m marketing fund.
Rodrigues said: "I am determined to do my utmost to ensure that tourism, already Britain’s fifth largest industry and third biggest earner of foreign exchange, makes a major contribution to the rebalancing and rebuilding of Britain’s economy.’’
Christopher Rodrigues became chairman of Visit Britain in January 2007. He is also chairman of International Personal Finance, The Windsor Leadership Trust and The Almeida Theatre and a council member of the National Trust.
