There's got to be something strange in the soil at a Taranaki high school, with four former pupils being selected in the All Blacks' Northern Hemisphere tour.
Barrett brothers Beauden, Scott and Jordie along with Liam Coltman were all named last month in Steve Hansen's 39-man squad.
Crusaders lock Scott, 22, has the opportunity to possibly make his debut this weekend in Chicago against Ireland with both Brodie Retallick and Sam Whitelock ruled out due to injuries.
Francis Douglas Memorial College deputy principal, Tim Stuck, and teacher Steve Simpson both coached the school's 1st XV team together and separately between 2004-2015.
All five Barrett brothers attended the school, each carving out time on the field for the 1st XV.
So naturally, we wanted to know which Barrett brother was better.
"For me Scotty Barrett certainly showed signs of progressing further as did the others. I thought he was a pretty class player to be honest," said Mr Stuck.
The eldest of the Barrett boys is Kane, 26, who played for Super Rugby franchise the Blues for two years and Taranaki before he was ruled out of the game in 2014 due to concussion.
"They were all good (Barrett brothers). They all have their great qualities. Obviously Beauden has gone onto being the first All Black but Kane was a different kind of player," said Mr Simpson.
The father of the five talented footballers, Kevin 'Smiley' Barrett, represented Taranaki and played for the Hurricanes from 1996-1998.
He was known for his tough and ruthless approach around the breakdown when he played lock and flanker, his style of play mimicked by son Kane who also represented Taranaki.
"[Kane] was a real tough, nuggety forward like his dad, it is very hard to compare," Mr Simpson told 1 NEWS NOW.
Young Canterbury utility back Jordie, 19, has been included in the All Blacks' end of year tour but will not play any games.
He has taken on an apprentice role similar to Ardie Savea who travelled with the All Blacks team at the end of 2013 to soak up the experience.
"Jordie, the youngest, has come through looking now that he could be an All Black and Soctt has made the squad as well," Mr Simpson marvelled.
Beauden's good friend Scott Crocker played alongside him for two years in the college's 1st XV and is now teaching physical education at the college.
"They (Kane and Beauden) sort of led both those teams (2008-2009). Coming in at sixth form with Kane as captain it was a bit of an eye-opener. He was always a physical and hard-nosed player," said Mr Crocker.
"I think Beaudy scored 32 tries that year (2009), it was bloody good playing with them."
Otago captain and hooker Liam Coltman, 26, was called into the All Blacks for a week back in 2013 as part of an apprentice role but has now cemented a spot in the squad.
"I remember Liam making the 1st XV team when he was only year 11," said Mr Simpson.
"He proved to be one of those players that just gives you 100 per cent. Had a fantastic attitude, trained hard, he was always going to do well it just took a while."
Beauden and Coltman both played together in the 2007 1st XV team for the college.
Mr Stuck credits the players' humble upbringing in succeeding and moving onto playing professional rugby.
"I do think the lads that come from this province have certainly got a work ethic that can challenge anyone around New Zealand."
The small Taranaki college with about 750 boys has several other former students currently playing professional rugby in New Zealand.
Former 96 capped veteran All Black Conrad Smith also attended the school and played in the 1999 1st XV team.
