After eight years, former Prime Minister Helen Clark is leaving the United Nations Development Programme - and farewell messages are flooding in from UN staff around the world.
In a message to her colleagues Miss Clark said: "These have been wonderful years for me".
She praised the work of the UN saying "the world is a better place for the work of UNDP over the past 51 years".
"I leave convinced that UNDP has a vital role to play in supporting countries to meet their national development aspirations and to achieve the globally agreed development, environmental including climate action, and other agendas.
"As well we play an important role in advancing democratic governance, human rights, and risk-informed development."
She says she will continue to be an advocate for development, climate action action, and other causes - and she'll still be busy on social media.
"All the best to you all, and I will always treasure the memories of my years working with you."
Miss Clark, 67, has not given any indication as to what she will do next with her career or whether she will return to New Zealand to live. Her husband Peter Davis has continued to live in the couple's Auckland home during her time based in New York.
