John "Jock" Munne Moreland (b 11 January 1921 Wanganui d. June 2012) was a New Zealand marine biologist and ichthyologist who worked at the Dominion Museum, later the Museum of New Zealand Te Papa Tongarewa, in Wellington.
He graduated with a Bachelor's degree in Biology from the Victoria University of Wellington in 1958.
McCann's interest was in marine mammals so he tasked Moreland with curating the collection of seabirds.
This resulted in him becoming responsible for the New Zealand Bird Banding Scheme, which the museum oversaw.
This work resulted in the publication of A guide to the larger oceanic birds (albatrosses and giant petrel) of New Zealand waters.
