The article is generally reliable and trustworthy, as it provides accurate information about Jacinda Ardern's resignation from her role as New Zealand Prime Minister and the reactions from world leaders, including US President Joe Biden. The article also includes quotes from Ardern herself, which adds credibility to the story. However, there are some potential biases in the article that should be noted. For example, there is a lack of exploration of counterarguments or alternative perspectives on Ardern's decision to resign; instead, the focus is largely on praising her leadership and accomplishments while in office. Additionally, there is no mention of any potential risks associated with her resignation or what could happen next for New Zealand without her at the helm. Finally, it should be noted that while Albanese's opinion piece is mentioned in the article, his views are not explored in depth or presented alongside other perspectives on Ardern's resignation.
