The body managing millions of dollars of multiple-owned Maori land says there are 38,000 beneficiaries it is actively trying to track down.
The Office of the Maori Trustee appeared before a Maori Affairs Committee in Parliament on Wednesday.
The trustee administers or manages about 100,000 hectares of Maori freehold land.
There is $6 million being held in a common fund for beneficiaries they do not have an address or contact details for.
Maori Trustee Jamie Tuuta says one of its key goals is to find these people.
He says their input is needed into how to manage the funds and they will be financially better off for it.
Mr Tuuta says it has the correct contact details of only 65% of its beneficiaries.
