Re-invention is the name of the game.
Events and organisations are continually having to re-invent themselves. Pop stars like David Bowie did it and, this being an election year, our political parties are also at it (though they might choose to call it "rejuvenation").
Super Rugby rejigs almost every season to retain its appeal, and the Wellington Sevens (union) and Auckland Nines (league) have undergone the re-invention process.
Here in Whanganui we have just had the 10-day New Zealand Masters Games, a wonderful event that provides fun, camaraderie and a big visitor influx to the city.
But the number taking part has been dwindling for more than a decade, and the spectre of re-invention is never far away.
