Dilworth School's issued an apology to the victims of alleged historical sexual abuse

Two more people have been arrested in relation to alleged sexual offending at the Auckland school.

A 73-year-old man is charged with three counts of indecent assault, and a 39-year-old with three of sexual violation.

A further two people already before the court are now facing further charges.

Dilworth Trust Board Chair Aaron Snodgrass says none of the individuals continue to be connected to the school.

He says they continue to support police in their investigation, and deeply regret the abuse some ex-students suffered while in their care.
