Boyd fears long-term effect of New Zealand brain drain

New Zealand rugby bosses should be concerned about the loss of expertise from rugby coaches moving overseas because of limited career opportunities at home, departing Wellington Hurricanes coach Chris Boyd has warned.

The 59-year-old Boyd has been appointed as the director of rugby for English club Northampton and takes up his new role at the end of the upcoming Super Rugby season.

Despite dominating world rugby, New Zealand has just five top-tier professional teams, all of which feed into the world champion national side, and Boyd said it was simple mathematics once a coach reached that level.
