Carter has been signed by watchmakers TAG Heuer, who have made him a brand ambassador.
The Swiss company has announced via Twitter: "Are you ready for fantastic news? We are so proud to present New Zealand rugby super player Dan Carter as our newest TAG Heuer Ambassador".
The company's other ambassadors include the American football quarterback Tom Brady and football superstar Cristiano Ronaldo.
Land Rover dropped Carter last month, a decision Carter said was not suprising.
