I want to know the answer to the following question:
What's the name of the agreement that ended with the start of Samoa's independence from New Zealand?
All the background I'm provided with is that "After repeated efforts by the Samoan independence movement, the New Zealand Western Samoa Act 1961 of 24 November 1961 granted Samoa independence effective 1 January 1962, upon which the Trusteeship Agreement terminated.". Is that enough to answer the question?
Answer: yes
