Officials of the Tertiary Education Commission have been accused of wasting the Maori Affairs Select Committee's time and told to reappear when they're better prepared.
The commission failed to provide written details about how tertiary chief executives are appointed.
The information was requested by the committee to help determine whether there are grounds for an inquiry into the way the former CEO of Te Wananga o Aotearoa was let go.
Bentham Ohia's contract ended at the end of last month but he's calling for an investigation into the process, saying there were flaws in the way he was voted out.
The committee's education spokesperson, Nanaia Mahuta, says its members time was wasted because the officials failed to bring written details about processes carried out.
She says members are unable to fully consider whether there are grounds for an investigation until they have the information in front of them.
Officials from the commission and the Ministry of Education have been invited back in three weeks.
