I don't think the reaction was hysterical, the united States ranks 14 out of over 200 countries for most deaths to COVID per capita, and we don't even have high population density.
Makes you wonder about deaths counts too?

No saying people aren’t dying of Covid, just wondering how accurate the numbers are? And is Covid as the cause correctly attributed?
Would be better to compare excess deaths per capita (instead of reported COVID deaths)
Also you're comparing apple to oranges. Contrary to most Western countries, New-Zealand focused on sealing their country away, meaning they didn't have to have harsh lock downs for a long time.
