Mary Isabel Fraser (20 March 1863 - 18 April 1942) was a New Zealand teacher, school principal and educationalist.
Throughout her career as a teacher and then as a school principal, she was a strong advocate for girls' education.
She is also known for having introduced, after returning from a trip to Yichang in China, the first kiwifruit seeds in New Zealand, in 1904.[1] This allowed nurseryman Alexander Allison to grow plants from these seeds,[1] and it was from this experience that the worldwide kiwifruit industry developed.
