Liddington-Tamati impressed scouts at the 2021 New Zealand Māori Rugby League tournament, but was unsure as to whether he had made the cut.
His parents Te Rei and Trace Liddington were the first to find out the news.
"I wasn't even at home at the time my mum got a call from ESP, so she had to ring me to tell me. I was with some of my friends, and we were all stoked. It was pretty cool to hear," Kleeshae said.
"Mum is proud. She is just so excited for me knowing that this is my dream, and this might be where my dream starts."
The training camps will be hosted by the Brisbane Broncos, Wests Tigers and Melbourne Storm in Auckland in July, October and December.
"I want to learn as much knowledge as I can to make me a better player in general and hopefully be selected for higher teams," Liddington-Tamati said.
ESP Trust is a charitable organisation that provides sport-based life education coaching clinics to young and aspiring rugby league players.
Karamu High School principal Dionne Thomas said her school prided itself on providing a melting pot of opportunities.
"It is exciting to see how Kleeshae has found his passion and is pursuing it with all he has. He has also thrown himself into kapa haka at school," she said.
