whakatīeke
1. (verb) to stretch oneself, exert one's strength to the maximum.
Kore rawa pea e ekea taua taumata mutunga kē mai nei o te ekieki, engari ko te pata kē ia o te whakatīeke, ka teitei haere kē ake, ka ātaahua kē ake te tirohanga atu (HM 4/1993:9). / That extremely high standard will probably never be achieved, but the advantage of stretching upwards is that the view is more beautiful.
