"We found out three weeks ago that the Tall Blacks would be coming. There are eight players here," Manklelow said.
"We thought it would be great to open up for the community to come down and see what we have. All the students have entered in the slam dunk competition. They can join the players on the Dark Ride in virtual reality too."
Lynmore School student Claudia Dunn, 6, was one of the large crowd.
She plays basketball every Monday after first learning the rules two years ago.
Tall Blacks centre Rob Loe said the team normally had "one or two" meet and greet opportunities with the public during training camps.
"Nowadays we are in pretty short camps so it is hard to get all the stuff we need to do on the court in, too. It is pretty full on, with training and video sessions and all the other things."
He said the team arrived on Sunday night and would return to Auckland on Friday morning after the Thursday night match.
Shooting guard Reuben Te Rangi said it was "awesome" getting out to see the kids in Rotorua.
"It's always fun getting out seeing what the rest of the country thinks about our basketball."
The Tall Blacks and the Hong Kong team were officially welcomed to Rotorua later in the morning at the match venue, the Energy Events Centre.
