He is proud of the young talent coming through the Bay system, particularly the three latest New Zealand reps.
"Henry was a small kid so to compete with his peers he had to develop an unbelievable short game. Suddenly, he shot up and is over six foot tall and is up there with hitting the ball but has retained his excellent short game. That is what has made him such a good young golfer.
"Harry's prodigious length off the tee is his strength. If he has a weakness it is a little self-confidence he needs to work on. He doesn't realise how good he could be.
"I stated it a year ago that it was not a matter of whether Alanna would became a national rep but just a matter of when. She has such a fantastic game and now she has the putting right. She has just got a lovely attitude and a fabulous temperament."
The World Junior Golf Team Championship is for golfers under-18 years. It began 22 years ago but took until last year before a junior girls championship was held with the boys championship.
The 2015 event will feature a strong field of the best players from 20 countries covering six continents. Norway are the defending boys champions after winning with a 21-under par team total of 831. Host country Japan won the inaugural girls event last year.
