Goodhue, who just won the Super Rugby title with the Crusaders, has signed a two-year contract with French Top 14 club Castres Olympique.
The 28-year-old said he will move to Europe after completing rugby commitments in Aotearoa.
He didn't make the All Blacks Rugby Championship squad, meaning he's unlikely to make the World Cup squad but he was picked for the All Blacks XV squad's upcoming tour to Japan.
"Playing for the Crusaders and the All Blacks has literally been a dream come true for me," Goodhue said.
