When 6-year-old Eddie Writes decided the world needed a little more kindness, he did the only thing he thought would work ― he wrote to his city's mayor and asked for help putting on an annual Kindness Day." Much to Eddie's surprise, Wellington Mayor Justin Lester wrote back. On Nov. 16, New Zealand's capital city will be holding its first Manaaki Day (manaaki being the Maori word for kindness), taking Eddie's ideas of how to encourage and celebrate charitable acts ― "We can buy toys for children that don't have any," for example ― to improve the social well-being of citizens. The mayor's support for the new holiday is part of a new wave of progressive, child-centred politics sweeping New Zealand, led by Prime Minister Jacinda Ardern, herself a new parent. Ardern was met with thunderous applause at the United Nations last month for her speech calling for kindness and cooperation from world leaders. Watched by her partner and their then 4-month-old daughter, Ardern pledged New Zealand would be "a kind and equitable nation where children thrive, and success is measured not only by the nation's GDP but by better lives lived by its people." Ardern also has her sights on New Zealand's growing housing affordability problems. The country's housing market is heated, with home prices rising more than 60 percent in a decade. Ardern blamed speculation from overseas buyers. The government responded with a law that took effect Monday banning foreign buyers from purchasing existing properties.
