[1] The regiment was progressively expanded and by the end of the war had batteries all over the upper North Island.

After the war it was decided that only the defences at Lyttelton should be kept in an operational state by a small peacetime garrison.

The armament and equipment were placed on a care and maintenance basis, while the regiment was reduced to a cadre.

Over the coming years, the equipment was scrapped and much of the facilities and land were sold off.

The regiment eventually dropped to a single quartermaster sergeant, but continued to exist on paper until it was formally disbanded in 1967.
