In an investigation of all New Zealand private schools the NZ Herald found that more colleges than ever are charging $30,000-plus in tuition fees with an average 4.2% tuition rise this year, the smallest increase in three years.

Independent Schools of New Zealand CEO Guy Pascoe told Mike Hosking the jump in fees can be attributed to rising cost of living, but that hasn't impacted tuition numbers.

"We still see pretty strong demand across our schools," he said.
