They let New Zealand and Hawaii design the view of earth for the official flag.

(But also I look at this a lot and think about my ambition to sail across it. Radar, satellite phone, all the tech or not... that is a lot of big angry water.)

@futurebird For Pasifika people this is the case: "for many Pacific Island peoples, the Ocean is a single living, moving, sacred entity and the bloodline of the people."

While most nations think of territories on land masses as home, for Pasifika the ocean is home as much as its islands are.

My family subsisted on the ocean's bounty; we worshipped gods and goddesses who were likewise the ocean (Nā-maka-o-Kahaʻi and Kanaloa) and of the ocean (Kamohoali’i and Ku'ula)

@futurebird Meant to add this wrt to "angry" ocean. The Pacific is rather calm in comparison to the Atlantic as you can see from the map below. Compare it to the Atlantic wave map at earth nullschool net: https://earth.nullschool.net/#current/ocean/primary/waves/overlay=significant_wave_height/orthographic=328.28,-0.68,177
