The All Blacks' support team of wives, partners and children are starting to trickle into Japan as the All Blacks edge closer to the knock-out stages of the tournament.
Here are a few of the women backing black from the sidelines in Japan and back home.
Titled the "first lady of New Zealand rugby" by media when she tied the knot with All Blacks star Beauden Barrett earlier this year, Hannah Barrett is arguably the highest-profile partner of the New Zealand side.
Hannah and Beauden got engaged in Fiji last year before saying "I do" in January on the Hauraki Gulf's Rakino Island.
The 24-year old, who boasts 56.6k followers on Instagram, has so far voiced her support for Beauden and the team from New Zealand but looks set to join her husband in the coming weeks.
All Black halfback TJ Perenara's wife, Greer Perenara, might not yet be in Japan but she hasn't held back in her support for her husband on social media.
Greer recently made headlines after she hit back at broadcaster Sean Plunket for calling TJ "woke".
The couple tied also the knot earlier this year with an unconventional surprise wedding after dating for nine years.
TJ and Greer invited friends and family to attend what they thought was an engagement party before the pair announced it was actually their wedding.
Greer will likely jet to Japan in the coming weeks, but for now, she's being kept company by the couple's fur baby, Roni.
Phoenix Karaka is no new name to the New Zealand sporting scene. And long-time girlfriend of Patrick Tuipulotu, nor is she new to the team of partners.
Both captains of their domestic teams - Karaka of the Mystics and Tuipulotu of the Blues, the power couple could soon both boast World Champion titles.
Karaka was part of the Silver Ferns side to claim gold at the Netball World Cup in July and will be keen to witness her other half claiming the same top-of-the-world glory at the Rugby World Cup.
The Ferns defender won't be able to join Tuipulotu in Japan just yet though having been named in the New Zealand side to play the Australian Diamonds in the Constellation Cup. Her Silver Fern duties finish just one week ahead of the Rugby World Cup grand final.
Sonny Bill Williams and long-time partner Alana Williams have three kids together - Imaan, Aisha & Zaid - recently announcing they would be expecting a fourth early next year.
It's unknown what the family's travel plans are yet, however, they too are expected to join SBW later in the tournament.
Angus Ta'avao is one of few the All Blacks lucky enough to already have his family with him in Japan.
Wife Kristyn Ta'avao, a freelance makeup artist, and two-year-old son Leo were recently snapped on Instagram with Angus in Oita where the All Blacks played their second pool match against Canada on Wednesday night.
Angus posted an adorable picture to his story with Leo in a mini No.3 All Blacks jersey.
The couple joins the group of recent weds, having tied the knot earlier this year in Kumeu.
Saskia Savea is the wife of All Black Ardie Savea.
The couple are parents to daughter Kobe and fur babies Kota and Kylo. They also both co-found and direct their own company 'Ardie Savea Clothing'.
While not in Japan, Saskia has been vocal in her support, most recently backing Ardie as he took to the field as the second-ever player to wear goggles.
"Words cannot describe how proud I am of you [Ardie] Embracing rather than ignoring," she wrote on Instagram.
Also supporting from home with one-month-old baby boy Luka Fox, is Aaron Smith's partner Teagan Voykovich.
The couple welcomed baby Luka in August on the same day Smith was named in the All Blacks' Rugby World Cup squad.
Voykovich shared an image of Smith cradling Luca on social media before the All Black halfback left for Japan, saying the goodbye was "by far one of the hardest things we've ever had to do".
"I'm going to miss you so much (especially my pro night time nappy changer)," she wrote.
One of the younger members of the All Blacks family crew is 22-year-old Evie Burdon - girlfriend of All Black fullback George Bridge.
Burdon, a law student at the University of Canterbury, is set to take some off from her studies and join Bridge in Japan. She last posted a picture with her All Blacks partner three weeks ago with the caption "see ya in Japan".
Wife of All Blacks captain Kieran Read, Bridget Read is likely to make an appearance at the Rugby World Cup.
In fact, Bridget will soon become a familiar face in the Japan stands as the Read family prepare to move there after the World Cup.
Earlier this year Kieran confirmed he will join Japanese club Toyota Verblitz on a one-year contract after the tournament and will take Bridget and their three children with.
