Dragons RFC full back Huw Anderson crossed the whitewash as Wales and New Zealand shared 11 tries in a breathtaking encounter in the opening Pool A clash of the Under-20 World Championship - but it was the Baby Blacks who secured the spoils with a 41-34 victory at Athlone Stadium, Cape Town.
It was a record score for Wales against the Baby Blacks while five tries ensured they took two bonus points, despite the defeat.
Louie Hennessey crossed twice while full-back Anderson and 17-year-old Steffan Emanuel also went over at Athlone Sports Stadium.
Wales battled hard throughout and, though an opening victory never seemed likely, they ensured a nervy ending for New Zealand when Macs Page’s 79th-minute try cut the deficit to just seven points.
Wales are next in action on Thursday (June 4) when they face Spain Under-20s.
