The second silver coin in the Czech Mint's series entitled Ice Age depicts the colossal moa bird.

Seventy million years ago, a piece of land broke away from Antarctica and drifted to the Pacific Ocean. There were no mammals living there – no grazing herbivores or dangerous predators – and the island, which centuries later would be named New Zealand, became home to a remarkable animal community. It was dominated by flightless moa birds. In a safe environment rich in food, they were able to evolve undisturbed. They did not need to fly, so they did not need to be light, and nothing limited their growth. They were among the largest birds in the history of the planet. Depending on the species, they could grow to a height of 3.6 meters and weigh 230 kilograms. Females, which were half as tall and three times heavier than males, laid one or two eggs with a volume of 4.5 liters, which is equivalent to 80 chicken eggs. Unlike today's ostriches, moa birds had no wings – they did not even have remnants of wing bones. They had a small head and a wide, curved beak. While smaller individuals grazed on grass and berries, larger ones fed on the leaves of shrubs and low trees. Mushrooms were an integral part of their diet. Moa birds survived the Ice Age, but disappeared six centuries ago. They were exterminated by the indigenous inhabitants of New Zealand – Maori hunters.

Medal maker MgA. Tereza Eisnerová depicted a flock of moa birds on the reverse side of the coin. While one sits on eggs, the others look around the surrounding tropical landscape. The inscription gives the Latin name of the prehistoric species, DINORNIS. The warm atmosphere of New Zealand, which thousands of years ago, unlike areas closer to the poles, was not covered by ice and snow, is complemented by green-brown enamel. The reverse side depicts the harsh landscape of the Ice Age. As the coins of the Czech Mint are issued with the foreign license of the island of Niue, they also bear its national emblem, the nominal value of 5 DOLLARS (NZD) and the year of issue, 2025.

The coin is supplemented with a thematic brochure.
