A pioneering private investigator, bestselling author and expert in human behaviour, Julia Hartley Moore has spent nearly three decades uncovering the truth behind some of life’s most complex personal and professional challenges.
As one of New Zealand’s most recognised investigative professionals, Julia has built an international reputation for her expertise in relationships, deception, trust and human behaviour. Through her company, Julia Hartley Moore Limited, she leads a team of licensed investigators operating across New Zealand, Australia and the United Kingdom, handling cases ranging from infidelity, scams and child custody disputes to corporate investigations, surveillance and security matters.
Julia’s insights into human behaviour have made her a sought-after commentator on issues involving relationships, deception and personal resilience. Her expertise has been featured by leading international media organisations including the BBC, Good Morning America, The View, Daily Mail and Huffington Post. In New Zealand, she is a familiar voice and face across television, radio and print, appearing on programmes including Breakfast, Seven Sharp, 1News, Sunday and Radio New Zealand’s The Panel.
Her path to success is a remarkable story of determination and reinvention. Dyslexic and unaware of her learning differences until adulthood, Julia left school at 14 and became a mother at 15. Refusing to let circumstance define her future, she forged her own path, overcoming significant challenges to build a globally recognised business and become one of New Zealand’s most successful female entrepreneurs.
Julia’s fascination with investigative work began while working at Harrods in London under the ownership of Mohamed Al Fayed, where an early investigation sparked a lifelong passion for uncovering the truth. After returning to New Zealand in 1996, she became the country’s first woman to own a private investigation company, helping break new ground in a traditionally male-dominated profession.
Alongside her investigative career, Julia is an internationally published author whose books have reached readers around the world. Her titles, Julia Moore PI, Infidelity: Exploding the Myths and Suddenly Single, published by Penguin and HarperCollins, have been translated into 15 languages. Drawing on decades of real-world experience, her writing explores relationships, resilience and the realities of human behaviour with honesty, insight and practicality.
More recently, Julia has expanded into documentary and television production. Through her production company, Blonde Ambition, she co-produced the acclaimed true-crime series Polk: The Trial of Philip Polkinghorne and continues to develop investigative and true-crime projects that explore the complexities of people, relationships and the pursuit of truth.
Recognised for her unique combination of investigative expertise, entrepreneurial achievement and personal resilience, Julia Hartley Moore offers rare insight into what motivates people, how trust is built or broken, and the determination required to overcome adversity and create lasting success.
