Peter studied art and jewellery making in both the Netherlands and New Zealand. He is very active in his own art practice, making collections for national and international exhibitions. His philosophy in arts education is that each individual (student) is unique, therefore has potential for artistic expression. His passion for jewellery and the arts transfigures lessons into experiences.
Peter is both a contemporary artist and a craftsperson. Ideas that make distinctive connections with jewellery are the inspiration for his work, and a recent 20-year survey exhibition at Pataka, Porirua highlighted his interest in language, through a series of engaging pieces displayed with accompanying sound. He exhibits with dealer galleries throughout New Zealand and the world. His work, philosophy and ideas have also been the subject of a book, Choices of the Hand, a survey of work from New Zealand jeweller Peter Deckers, introduction by Stevan Eldred-Grigg, published by First Editions, Wellington (supported by Creative New Zealand).
