Lol. OK then Te Kaha. Fat fingers are the main cause.
On a more important note : Another contributor suggested you read Graham Lowe's book. Lowe refers to being caned at school for wanting to play rugby league in preference to rugby union when growing up in New Zealand.
And the fact you are a moron.
"Lowe and Behold" is referring to life 60+ years ago, and refers to an individual school. There were lots of instances of that happening.
However, your claim was that NZ Rugby prevented League from being played in school. This book doesn't suggest that at all. Once again you have failed to back up your claim.
