 During Hansen 's tenure , the WRU implemented a significant change in the structure of the game domestically . Regional teams were introduced as a tier above the traditional club @-@ based structures in 2003 , and the five ( then four ) regional sides became the top level of domestic professional rugby in the principality . At the 2003 World Cup , Wales scored four tries in their 53 – 37 loss to New Zealand , and also lost to the eventual tournament winners , England , in their quarter @-@ final , despite <unk> them by three tries to one .
