The £3 million grant aims to ensure the British & Irish Lions' first women's team is not England in name only.
However, there are concerns about the potential balance of the squad, given that England have won 17 of the last 25 Five Nations titles.
As a result, Lions sponsors will provide funding to develop players and coaches in all home countries.
In addition to England, funding will also be provided to Wales, Scotland and Ireland to “level the playing field”.
Former England flanker Maggie Alfonsi said: Action was needed to make the Six Nations more competitive The Red Roses are on track to win their sixth straight title after defeating Scotland 46-0 in Edinburgh last Saturday.
Wales have never won a Six Nations and are bottom of the table this year with three defeats.
Welsh Rugby Union says the new funding from Royal London will pay for five new staff to strengthen its women's pathway coaching, including a performance coach, set-piece skills coach and head of physical development. Announced.
We will also invest in programs aimed at identifying talented players from across Wales, as well as international players who are eligible to represent Wales.
Nigel Walker, WRU Executive Director of Rugby, said: “This is vital and welcome funding that we will maximize in a way that has an immediate, direct and positive impact on our performance pathway in the women's game. We plan to do so.”
“We will continue to focus on talent identification and development, and will also introduce significant new additional coaching, development and science-based support.”
The last time Scotland won the Home Nations Championship (held between the four unions) was in 1998.
Scottish Rugby Union aims to hire two coaches and provide additional camps and training matches for the under-18 and under-20 women's teams and the national academy.
Ireland are the only team apart from England and France to win the Six Nations title in 2013 and 2015, but finished bottom last year.
The Irish Rugby Football Union will also host additional age-specific camps, as well as working with universities to identify player talent and develop a coaching scholarship programme.
The Rugby Football Union will use part of the grant to further develop its current programmes, including skills work.
Lions CEO Ben Calvery said the grant was a “significant investment” to support the growth of the women's game across the country.
The tour to New Zealand will take place in September 2027. The full schedule is yet to be finalized but will include three tests against world champions the Black Ferns.
