A trio of yellow cards tainted the New Zealand Under 20s win over Wales in the World Rugby Under-20 Championship in France.

The Baby Blacks ran in five tries to one in the 42-10 win, backing up their 67-0 thrashing of Japan.

Loose forward Tom Florence (high tackle), winger Bailyn Sullivan (deliberately knocking the ball down) and second five-eighth Tanielu Tele'a (no arms tackle) were all sent to the sin-bin for 10 minutes during the match.

The New Zealand Under-20 side's victory over Wales in France on Monday morning (NZ time) means they remain unbeaten through two matches.
