1st Brigade (New Zealand)

The 1st Brigade is currently the largest unit of the New Zealand Army, and contains most of the army's deployable units. The brigade was formed on 13 December 2011 by amalgamating the 2nd Land Force Group and 3rd Land Force Group. Its establishment formed part of the 'Army 2015' package of reforms.

Previous 1st Brigades in the New Zealand Army have included a brigade in the Middle East and France, 1916–19, a home defence formation active during the Second World War (part of the North Island home defence 1st Division), and a 1 Brigade / Integrated Expansion Force formed to direct three Territorial Force-formed battalions in the 1970s and 1980s.

First World War
The 1st Brigade came into being in Egypt in early 1916, when the New Zealand and Australian Division was re-organised in the wake of the Gallipoli Campaign, and the New Zealand Division was formed. Under the command of Brigadier General Harry Fulton, the brigade initially consisted of four infantry battalions, being the 1st Battalions of the Auckland, Canterbury, Otago and Wellington Regiments. In this configuration, the brigade was transferred to the Western Front in Europe, and fought through the Battle of the Somme before the New Zealand Division was restructured. This saw the brigade reconfigured, swapping its two South Island battalions (the 1st Canterbury and 1st Otago) with the two North Island battalions (2nd Auckland and 2nd Wellington) of the 2nd Brigade. This placed all the North Island battalions in the 1st Brigade while all the South Island formations were in the 2nd Brigade. Following this, the brigade fought in the Battle of Messines and the Third Battle of Ypres during 1917, before helping to turn back the German spring offensive in early 1918, and then taking part in the Allied Hundred Days Offensive in the final months of the war. After the armistice, the brigade was committed briefly to post-war occupation duties until the New Zealand Division disbanded in early 1919.

Second World War
The 1st Infantry Brigade was re-established prior to the Second World War as a Territorial Force formation manned by part-time reservists. At the outbreak of war on 3 September 1939, it formed part of the field force for the Northern District. At this time it commanded the 1st Hauraki Regiment (headquartered at Paeroa), 1st North Auckland Regiment (Whangarei) and 1st Waikato Regiment (Hamilton).

On 1 November 1941, the 1st Brigade became part of the newly formed Northern Division in the Northern Military District. The division's two brigades were the 1st and 12th Brigade Groups. Later the Northern Division became the 1st Division. The 12th Brigade Group was one of the new headquarters, and both these units continued to be manned by reservists. During early 1942, camps were constructed for the 1st Brigade Group in South Auckland and the 12th Brigade Group at Kaikohe. The 1st Brigade subsequently moved to a camp near Warkworth.

After the threat of invasion passed, the 1st Brigade and the other home defence formations were reduced in size during 1943. By the end of the year the seven brigade (including 1st Brigade) and three divisional headquarters comprised a total of 44 personnel, with the soldiers assigned to the Territorial Force units they once commanded having been demobilised. All of these headquarters were disbanded on 1 April 1944.

Post-war
In 1950, Northern Military District directed four subordinate Area Headquarters, being Area 1 (HQ Auckland), Area 2 (HQ Tauranga), Area 3 (HQ Whangarei), and Area 4 (HQ Hamilton).

In 1963, the Combat Brigade Group (1st Brigade) was established, based on the Northern Military District headquarters at Auckland. Headquarters Northern Military District was disestablished in 1970 and the headquarters became home to Field Force Command.

Reformation
In 2011 the 1st Brigade was reformed from the headquarters of the 2nd Land Force Group at Linton Camp. Its role upon formation was to command all of the New Zealand Army's operational units, other than the 1st New Zealand Special Air Service Regiment.
