Meanwhile Mr Tan said if Mr Swart was missing his students, the emotion was mutual.
"He is a very special man," he said.
"He always has a smile. He is really servant-hearted. He's the sort of person who never complains.
"He just gets in there and does what needs to be done."
He said Mr Swart was a man of integrity, a man who did all he could and who put others first.
"He loves his students," he added.
"He coached volleyball for all those years, having coached in South Africa too, often taking Northland area schools teams to the South Island for tournaments.
"He always has a twinkle in his eye.
"He is an emotional man who never fails to bring us to tears when he speaks.
"He loves God with a passion, and his faith in God seems even stronger and deeper now.
"A lovely, lovely man."
