'We will always remember' - Black Ferns Sevens to honour Christchurch victims with names on warm-up tops

In an act of remembrance to the 50 lives lost in last month's Christchurch terrorist attacks, the Black Ferns Sevens' will wear special warm-up shirts for this weekend's Japan tournament.

After a gunman opened fire on two separate Christchurch mosques on March 15, claiming 50 lives and leaving dozens more injured, the Black Ferns Sevens will pay their own tribute to those killed.

The warm-up tops will each have the 50 victims' names printed on the back, as well as the hashtag 'They are us.'

Speaking to All Blacks TV, sevens star Niall Williams opened up about what it means to the side to be able to remember the victims.

"[It's] pretty special," she said.

"My message from us to you is that this weekend is about remembering your loved ones. Having them on the backs of our shirt, just seeing their names and playing with their names on the back of our shirts - is just about remembrance.

"You guys all come from different walks of life just like us, [you] all had dreams and hopes and aspirations.

"This is just a small gesture to show you guys that we do remember, and we will always remember.

"They are us."

New Zealand will face hosts Japan, Russia and France in pool play at the Japan Sevens this weekend.
