Uniform Buttons
Allied Mutual Insurance (AMI)

No maker’s mark.
The logo as seen on the buttons was changed in 2018.
This company started in 1926 as the South Island Motor Union. Problems with finance post the 2010-11 Christchurch earthquakes led to the sale of this company. Last year it was announced that the remaining branches were to be phased out.
Maestro
Does anyone recognise this logo? There is a electronics manufacturing firm based in the ACT called Maestro Pty. Ltd. since the 1980s, but their current logo does not match the button.
