The Havelock Work was an arts and spirituality movement in the small town of Havelock North, New Zealand, begun in 1907 by Reginald and Ruth Gardiner and Harold Large, and later embraced by the whole town. It culminated in the founding of the Smaragdum Thalasses temple, better known as the Whare Ra, the longest-standing temple of the Stella Matutina magical order.
