This is a chart we received from the Ministry of Health late last year, converted to an image file. It can be seen that the two most serious, by a long way, were Gastroenteritis/Colitis and Pneumonia.
Hospitalisations from Influenza totaled 116 — this was massively down on 2019–2020 (3468). Did the Wuhan-Fauci virus replace Influenza? It seems so, but hospitalisations from that during this 12 months period were miniscule also. Nevertheless, the Jacinda regime has resurrected Influenza as a cause for major concern with extensive advertising, and we’re not sure why, other than to keep people scared.
