History

The 3rd Battalion was formed by the amalgamation of the 3rd Auckland (Countess of Ranfurly's Own) and 15th Northland Regiments in 1965. In turn these Regiments trace their history back to the early volunteer militia of the 19th Century. For example, the Auckland Regiment was initially formed as the 1st Auckland Infantry (Countess of Ranfurly's Own) Battalion from amalgamation of the Victoria Rifles, New Zealand Native Rifles, Auckland Rifles, Gordon Rifles, Avondale Rifles and Newtown Rifles in 1898. In Northland a similar amalgamation took place in 1911.

At the outbreak of World War I both the Auckland and Northland Regiments provided a 250 man company to the 1000 strong infantry battalion that was raised from the Auckland region. This was named the 1st Battalion Auckland Regiment with 2nd and 3rd Battalions being raised later in the war. Three Victoria crosses were won by members of the Auckland Regiment.

During World War II the Auckland and Northland Regiments contributed mainly to the 18th, 21st, 24th and 29th Battalions. The Regiments were awarded 10 battle honours in recognition of the role played by soldiers in these battalions. The Northland Regiment also has strong links to 28th Maori Battalion.

In 1948 the two regiments were reformed as part of the post-war Territorial Force. The Artillery sub-unit of ANR can trace its lineage to 1/1 Battery and 4 Medium Battery of the New Zealand Artillery Regiment. Then, in 1964 they were amalgamated as a Battalion under the umbrella of a single Royal New Zealand Infantry Regiment and formed the current unit; the 3rd Auckland (Countess of Ranfurly's Own) Battalion Group.

In recent years, members of the unit have once more been called upon to volunteer for overseas service. In 2000 and 2001, many members of the unit served with NZBatt 3, the third rotation of Kiwi troops in East Timor. Soldiers from the unit have also formed part of two deployments to the Solomon Islands, the first in 2007 and the second in 2008.
