There are three significant interprovincial team events in New Zealand each year.
The annual matchplay tournament, originally the Freyberg Rosebowl, now the Toro Interprovincial, started in the early 1950s and is now played in early December. There's also January's under-23 teams championship at Taupo, which has evolved into virtually a fully-fledged national title because most of the country's top amateurs are in that age group.
And there's the SBS Invitational, the 31st edition of which is on next weekend at the Invercargill Golf Club's classy Otatara Links.
This is the most successful initiative by a local golfing authority in the history of the game in New Zealand. The genesis was a realisation that Southland could not support a professional tournament.
They did have the Southland Classic in the 1970s but after 1976 it just couldn't continue, so ambitious and enthusiastic locals came up with what has become the national teams strokeplay championship.
