Australias eSafety office only occurred because of the Christchurch shooting. The Australian government wanted a sniff of that moral panic, and said it needed the right to remove videos of the shooting from the internet. Thats the office that has been pushing for this law. You can draw a direct line from Christchurch to this event.

The Kiwis tightened their gun laws after the incident, despite having done pretty well with what they had until that year.

In both events, both governments paraded around saying shit like "Leading the world" such as Australia is once again doing here. Its much like Godwins favourite dictator going abroad to spruik his fantastic free holiday / political retraining resort. "World Leading" is the absence of any other quality terminology.

For Australias case, during the 00s and early 10s we actually had a really huge internet freedom movement. Previous attacks on the internet had bee repelled quite gracefully. It took such a moral panic to finally put Australia in its place, and now we are looking at a further consequence of that moral failure.

I'm not sure what you think is happening in New Zealand still. Your one example is a tightening of gun laws following a mass shooting. Something that virtually all Kiwis are in favour of.
