Warriors utility Lewis Brown will leave the club at the end of the season to join the Penrith Panthers and reunite with former coach Ivan Cleary.
The club made the announcement today after the two parties were unable to agree terms for a new contract.
Brown, who is off contract at the end of the 2012 campaign, and the club have accepted he will continue his NRL career on a three-year contract with Penrith from 2013.
The Christchurch-born 25-year-old Kiwi international said his decision to leave the club wasn't straightforward.
"It will be tough leaving. The Vodafone Warriors gave me my break to play in the NRL and also the chance to represent the Kiwis," he said.
