Spray plan 2 for Te Arawa Lakes Aquatic Weed Management 2024

Koheri ra! Kohera e!
Tutapa mai nuku, tutapa mai whiti
Kia rongo te pō, kia rongo te ao
Kia pā tata mai tō hau manawa
Ki tōku aronga manawa
Hai puta ki te whai ao, ki te ao mārama
Tihē Mauri Ora!
Toitū te wai, 
toitū te whenua, 
toitū Te Arawa
