In 2007, researcher Brent Kerehona claimed that uncertainty has arisen over whether Ngapuhi chief Moka Te Kainga-mataa actually signed; despite his name appearing on this document. A close inspection of the Treaty document itself shows no evidence of a signature or 'mark' next to Moka's name (which is written as 'Te Tohu o Moka'). Kerehona elaborates by inferring that it is clear by the accounts of Colenso (1890) that not only did Moka clearly express his concerns about the Treaty's effects whilst at the meeting on February 5, but that the discussion that he had with the Reverend Charles Baker, combined with Moka's final comment, should be taken into account.
