マスター系のテーブルに追加がある場合。

/Config/Migrations/以下のMigrationのプログラムに追記
‘up’した時にどうするかを追記。(‘down’のときも必要)

/**
 * After migration callback
 *
 * @param string $direction Direction of migration process (up or down)
 * @return bool Should process continue
 */
    public function after($direction) {
        if ($direction === 'up') {
            $Group = $this->generateModel('Group');
            $Group->save(array(
                'Group'=>array('name'=>'海外エージェント','key'=>'agent')
            ));
        }
        return true;
    }
