It wasn't that much of a surprise for him because NZ Croquet had approached him to do research and gather data on the inductees.
The inductees were honoured at a dinner during the code's annual meeting at Brentwood Hotel, in Kilbirnie, two Saturdays ago.
Former Rangatira club member Paul Skinley, now living in the capital, also was honoured.
Joe Hogan, of Gisborne, also falls within the sport's catchment area.
Prince, who was inducted into the World Federation of Croquet Hall of Fame in 2007, has won the NZ Open eight times and the national doubles 11 times, among other accomplishments as the first Kiwi to chalk up 100 appearances, as well as nine MacRobertson Challenge Series caps.
A champion on the global stage too, he is a life member of the national body as well as several other regions and clubs.
Born in 1897, Watkins (nee Serena Eliza Bishop) went on to clinch several national single and doubles crowns.
The four-times NZ Open champion, who died in 1967, combined to clinch three successive NZ Open doubles titles with her husband, the late Clem Watkins, from 1953-55.
Dubbed the "best female player the country has ever produced", Watkins, who adopted an upright sideways stance in executing shots, was a member of Hastings for more than 40 years.
Ross, dubbed the "Father of Triple Peels", was born in 1895 and died in 1975.
The poultry farmer cum schoolteacher, who represented New Zealand and won numerous national and international titles, also was inducted to the world federation hall of fame.
Only last month the Heretaunga Croquet Club was formed as a merger of the Hastings and Te Mata clubs.
The first recorded competition at Hastings club was in 1911 but it was incorporated in 1927.
The club had its last hurrah at its Stoneycroft, Omahu Rd, location on Tuesday, where a cocktail party also was held in honour of Prince's induction.
The club's members have affiliated to other clubs in the province and its $430,000 worth of assets has been gifted to the Hastings District Council to secure reserve land for croquet leasing.
Stephens says the Heretaunga club, in existence since last month, will add two more lawns to its seven existing ones.
The Te Mata club was 25 years old.
Prince says the merger is for the best and the code "is in good heart".
"It's sad that it's happened and isn't good for inter-club competition, but it's the old story of divided you fall, united you stand."
He notes that when he started playing four countries - England, Australia, New Zealand and later the United States - competed. Now the code has 30 nations registered and a lot more internationals played involving younger people.
