Mahere Pumahara Mamati Mamati (E tika ana ki te SFF-8472)

Ka whakaratohia e nga kaiwhakawhitiwhiti nga ihirangi mahara ID rangatū me nga korero tātari mo nga tikanga whakahaere o naianei na te atanga rangatū 2-waea (SCL, SDA).

Ko nga korero tātaritanga me te whakatikatika o roto, te whakatikatika o waho ranei ka whakatinanahia katoa, tae atu ki te tirotiro hiko kua whakawhiwhia, te tirotiro hiko tuku, te aro turuki o naianei, te tirotiro ngaohiko tuku me te aro turuki i te pāmahana.

Ko te mapi mahara whakamaarama matihiko e whakaatu ana i te mara raraunga e whai ake nei (Mo etahi atu korero, tirohia te SFF-8472).
