Pool D New Zealand rounded off a day of mixed form with a 26-0 win over France to top pool D and book a quarter final against England.

The French earlier opened up with a 28-5 victory over the Chileans. The France-Chile game was also notable for the fact that it was the first ever senior men’s international match to be refereed by a woman, Dana Teagarden of the USA.
