There's no one absolute point. I've been asked that question several times in the last few days and weeks. Was there a critical turning point? It's hard to put a finger on it. It happened some time in the last 20 to 30 years, and it was an accumulation of effort and events, but not a single one of these.
If I were to pin something down, sir, I'd bring it all back to education by Maori people of young people.
