It is believed that numerous nations competing in the tournament, including the four home nations of England, Wales, Ireland and Scotland, backed Australia's bid but numerous nations without a qualified team including South Africa and Argentina voted for New Zealand. It was the sixth time the Black Ferns have taken the cup home, and their Sevens counterparts also retained their World Cup title earlier this year as well.
Jubilant NZ Rugby CEO Steve Tew also praised the Australian bid.
New Zealand's pitch to host the six-week tournament received strong Government support from sports minister Grant Robertson, and a personalised video message from Prime Minister Jacinda Ardern, who expressed her delight at the outcome.
Wellington Rugby acting Chief Executive Matt Evans said the union was excited to host such an important Test match in such an important year.
"I don't think so", he said.
"We have the opportunity to showcase the best of women's rugby in front of the world's best supporters".
It was the best attended Women's Rugby World Cup to date with a record total attendance of 45,412, the most viewed with Ireland, France, the United Kingdom and US all recording unprecedented viewing figures, and also the most socially engaged, generating 45 million views across official tournament platforms.
"We congratulate New Zealand Rugby on its successful bid, and we are sure they will deliver a fantastic tournament in what will be the first Women's World Cup played in the Southern Hemisphere".
The tournament will be held in Auckland and Whangarei on New Zealand's north island. The final will be played at Auckland's Eden Park, which hosted the men's World Cup finals in 1987 and 2011.
Dr Palmer, the legendary Black Ferns captain turned New Zealand Rugby board member, led the winning presentation at a World Rugby council meeting in Dublin alongside former All Blacks midfielder and fellow NZR director Mark Robinson.
New Zealand won their fifth Women's Rugby World Cup in 2017 after they beat England 41 - 32 in a pulsating final at the Kingspan Stadium in Belfast, Ireland.
"It's also a great complement to New Zealand's ongoing hosting of the 8th International Working Group on Women in Sport secretariat, culminating in the 8th World Conference of the IWG in 2022".
"This is why I think the timing is right".
"There's lot's going on in New Zealand, there's the worldwide women's group on women in sport, there's the Government that's just released its strategy on women and girls in sport", Dr Palmer said.
"There is no better place".
