The only times there have been more New Zealanders involved was in 2002 and 2011, when the Warriors contributed plenty of home grown talent.
The situation tomorrow is a far cry from the 1980s, when only three Kiwis featured in grand finals across the entire decade.
It's a reflection of dramatically increased New Zealand participation in the NRL since then, which is down to a number of factors, including migration patterns, the relaxing of transfer regulations and Australian clubs waking up to the remarkable depth of talent on this side of the Tasman.
The Bromwich brothers will extend their niche as the only siblings from this country to play in a grand final, having featured together in 2016 and 2017.
Dane and Kurt Sorensen had many years together at the Cronulla Sharks in the 1970s and early 1980s but their time in the Sutherland shire never coincided with an NRL decider.
By playing in his fourth grand final, Bromwich also enters exalted company. Only four New Zealanders have achieved a quartet of NRL deciders.
Brent Todd (1987, 1989, 1990 and 1991) held the record for a long time, but the prop has since been joined by Jeremy Smith (2006, 2007, 2008 and 2010), Steve Matai (2007, 2008, 2011 and 2013) and Adam Blair (2006, 2007, 2009 and 2015).
The 29-year-old could also become the first Kiwi to have three premiership rings, going ahead of Todd, Smith, Matai, Sonny Bill Williams and a handful of others on two.
With nine Kiwis on show, there's also a chance that this country's Clive Churchill Medal drought could finally end.
Despite almost 140 appearances by New Zealanders in the NRL decider since the first in 1975, no one from this country has claimed the award for the grand final's best player.
It's partly because such individual honours tend to recognise playmakers and fullbacks - of which New Zealanders have been historically underrepresented in the NRL - and also because the judging panel is comprised of the Kangaroos selectors.
There have been some strong claims by New Zealanders over the years, particularly Matthew Ridge (1996), Tawera Nikau (1999), Benji Marshall (2005), Adam Blair (2009), Sonny Bill Williams (2013) and Jason Taumalolo (2017).
Depending on how the match unfolds, Jesse Bromwich, Asofa-Solomona, Waerea-Hargreaves or Taukeiaho appear to have the chance of scooping that award for this country, although the likes of Cameron Smith, Billy Slater and Jake Friend will be prohibitive favourites.
