Female sailors will have an onboard racing role in this weekend's SailGP round at Cadiz.
Tokyo Olympian Erica Dawson will compete on the New Zealand boat, currently sixth in the standings, with eight women in total set to race.
Nina Curtis (AUS), Katja Salskov-Iversen (DEN), Amelie Riou (FRA), Hannah Mills (GBR), Sena Takano (JPN), Andrea Emone (ESP) and CJ Perez (USA) will also compete.
Liv Mackay, the Kiwi crews second female, will continue to work as part of the offshore team this weekend.
SailGP introduced the Women's Pathway Programme this season, as part of its inclusion strategy to inspire change and provide opportunities across all levels of the sport.
Until now, women have held non-racing roles within the team, but for Spain, a sixth position has been introduced onboard the F50 catamarans, which will continue into next season.
"It is our responsibility, as a global league, to ensure we create a culture and sporting championship that has gender equity," says SailGP chief executive Sir Russell Coutts.
"It is no secret that there is currently an experience gap among women at the top of the sport and, so far this season, we have embedded female athletes in each of our teams to gain vital experience.
"But we recognise we have to go further to close the gap and work quickly to accelerate change, which is why we are taking this next step. It is imperative to break existing boundaries and create a more inclusive environment."
Brit sailor Hannah Mills says the experience will provide a great boost for women in the sport.
"I’m incredibly excited to be racing this weekend,” she says. “It's a really great step forward for the female athletes to be in the thick of it, witnessing it all, getting in and helping wherever we can - tactics, strategy and communications.
“I am really excited for that. The adrenaline rush is going to be massive - it already is, when we do the practice racing.
"It's also awesome for SailGP to have a strong vision and commitment going forward for the future of women's involvement in the league. It’s very exciting and I can't wait to figure out how we can make it all happen, how we can make it a success and how I can help drive it forward."
The New Zealand team has shown promise throughout the European leg of the series, but some poor performances have seen the Kiwis slip to the bottom half of the standings.
With the Sydney event just two months away, Blair Tuke says the final stop in Europe represents a chance for a reset, as they push for a place in the three-boat season-ending US$1m final next year.
"In general, we sailed pretty well at St Tropez,” he says. “It was pleasing to put in some good performances, it really felt like we were mixing it up with the top boats and deserved to be there through sailing well.
“Everyone is really geared up to finish off our European tour in good fashion. A lot of the team have been away representing Aotearoa for six months across this or the Olympics.
"It’s been a long stint, but everyone is looking to finish on a high and we need to for the overall championship as well."
