Whāia te iti kahurangi!
Strive for something of great value!
This comes from the whakataukī: Whāia te iti kahurangi, ki te tuohu koe, me he maunga teitei, which means Seek the treasure that you value most dearly, if you bow your head, let it be to a lofty mountain.
This whakataukī is about perseverance and endurance. Refusing to let obstacles get in your way while striving to reach your goals.
