The black and white wire looped into the left top switch / fuse carries has no fuse protection on it by the looks of it.
Also at the right no bushing used for the bare earth wire,
on the earth / neutral bar the wires are not terminated in an eye shaped way under the screws, but straight.
Typically you see these types of cables in older NZ installations from the 50's too.
Some cables are in very good condtions while other cables have very brittle insulation.
