Father Walter Lini Day is observed in Vanuatu every February 21, honoring the founding Prime Minister of the Republic of Vanuatu, Father Walter Hadye Lini. Lini, an Anglican priest and politician, founded the New Hebrides National Party in 1970, which later became the Vanua'aky Pati, advocating for Vanuatu's independence from French and British rule. Upon the country's independence in 1980, he became Prime Minister and served until 1991. His administration was marked by controversy due to its socialist ties and opposition to nuclear testing in the Pacific. The celebration of Father Walter Lini Day includes special remembrance church services and a wreath-laying ceremony at Lini's grave, reflecting on his significant contributions to the nation.
