kei tūpono
1. in case, just in case, lest perhaps.
Ka pai tonu te kohikohi i ngā kupu pēnei i te wā e whakamahia tonuhia ana, ka tāpiri atu ki ngā kupu e noho mai ana i rō papakupu Māori. Kei tūpono ka ngaro haere i roto i ngā tau, ā, mate ā-moa tonu atu (HM 2/1998:4). / It's quite good to collect words like this at the time they are still being used and add them to the words contained in Māori dictionaries, just in case they become lost over the years and die like the moa.
