The chair of Sir Owen Glenn's inquiry into family violence says the run of resignations from the project is disturbing but he is confident the investigation will proceed.
Three of the inquiry's four chairpersons confirmed on Wednesday they had left the $2 million inquiry being funded by the philanthropist.
It follows the resignations of the operations director and of the chief executive, long-time anti-violence campaigner Ruth Herbert.
The patron of the inquiry, Dame Cath Tizard says she is reconsidering her own involvement.
Inquiry board chair Bill Wilson told Radio New Zealand's Morning Report programme says the inquiry is not a vanity project for Sir Owen and says it can move on despite the changes.
Mr Wilson said he would be very concerned if Dame Cath left, and said she was meeting the inquiry's new chief executive, Kirsten Rei, on Thursday.
