A universal Cadet blouse was introduced in 1912 at the same time as the new territorial uniforms. The O’Sullivan’s in their book “NZ Army Uniforms and clothing 1910-1945” call this a type 2 blouse.
The collar has three points, one at the back, and each is secured with a button.
Close up of the pocket and 1911 pattern NZ Forces button.
The blouse is mostly unlined, there is a cotton lining to the collar.
On the inside of the lower right panel there is a manufactures tag for R. & W. MEEK, Auckland. The size 8 can be seen but unfortunately there is no readable date.
