"New Zealand Rugby, what is going on? What is your plan? What are we supposed to be doing right now?
"Am I supposed to wait? Am I supposed to sit on my hands and be quiet?
"You guys will hype our s*** and clip our ticket when we succeed, but right now, we're in the middle of another challenge and we're invisible, as per usual.
"A challenge for NZR, what's going on? But a challenge for the sports media, ask the question."
Soper says she's speaking out not only for herself, but on behalf of all of her "sisters" in women's rugby.
"I was asked if I felt like I was on my own in calling this out.
"No. Just like when we on the field, my sisters have my back. Even those who play in different jerseys have reached out. That's who I was speaking on behalf of. My voice is their voice."
Soper followed her initial tweet with another video a day later about her frustrations that she still hadn't heard anything from NZ Rugby.
In a statement to the Herald, NZ Rugby head of women's rugby Cate Sexton said work was being done around women's competitions.
"Women's rugby is at the fore of all our planning," Sexton said.
"We still have lots of work to do during these uncertain times, but preparation for RWC 2021 remains our priority and the Farah Palmer Cup is a key part of that. We will provide updates on all our competitions as soon as we have confirmation."
Sports administrators have called on the Government for specific funding into women's sport, which they say is in danger, and are hoping for funding in tomorrow's budget.
