In 1912, Logan joined the
New Zealand Military Forces and was posted to the
New Zealand Staff Corps as a temporary
colonel. He was already an experienced soldier of the New Zealand militia, known as the Volunteer Force, having raised the
Maniototo Mounted Rifle Volunteers in 1900. He had then served with the
1st Otago Mounted Rifle Volunteers four years later with the rank of
major, and was then promoted to
lieutenant colonel in 1908. Now, as a professional soldier with the New Zealand Staff Corps, he was appointed commander of the
Auckland Military District. Consequently, he sold the sheep farm at Maniototo and moved his family north to Auckland. He was later awarded the
Croix de Chevalier of the
Légion d'honneur in December 1919 "in recognition of valuable services in Samoa during the first year of the military occupation of that territory." Logan returned to New Zealand in January 1919. Although his temporary rank of colonel had been made substantive in 1915, he received no further promotions. He was condemned for negligence in handling of the influenza outbreak by a New Zealand commission of inquiry. His relatively harsh administration, and the errors he made, greatly affected Samoan relations with New Zealand. ==Later life==
