World Rugby Chairman Sir Bill Beaumont said there is unstoppable momentum building leading into the final months before Rugby World Cup 2021 kicks off.
"There is a very real, unstoppable momentum building behind the rise of women in rugby now and 2021 will be a year like no other, providing a unique opportunity to continue to accelerate the growth and profile of the sport, as women's rugby rightly is set to own centre stage this year."
Rugby World Cup 2021 Tournament Director Michelle Hooper said that with the announcement of the match schedule, anticipation of the tournament and the hotly contested action it will deliver, is expected to build significantly.
"It will give fans a taste of the excitement from the first kick-off and have them hooked to attend or watch every match of the tournament, in a schedule that promises to deliver an action-packed and intense competition."
Black Ferns captain Eloise Blackwell added "I remember how cool Rugby World Cup 2011 was and never dreamt that I would get the opportunity to play at a World Cup on home soil, let alone be kicking it off against Australia at Eden Park - it is going to be amazing."
