Can anyone recommend a good swimming instructor for a 9 year old child?

Kru Payu Swim they operate out of Bronco Kids Sport Club, two pools, one heated and indoor.  Great team.  Located inside the old city in the Northwest quadrant across the street from the Technical College and around the corner from Fern Forest Cafe and Good Souls Vegetarian Restaurant..  

Go to the public pools. Many times they have group traing sessions. 

I have been using a number of pools over the years, and at each of them there's invariably some swimming lessons going on particularly in the afternoon. Both group and one on one. So choose a pool convenient for you, and look at the notice board or ask the ticket office.
