There is no mention of the form not being needed anymore, the form will be updated in regards to the vaccination no doubt. Why should we have to fill out a form while on holiday providing such detailed information such as our flight numbers, dates of travel and even TIMES of travel when all of this information is probably loaded into our passport when checking in etc.
We are essentially being forced to provide unnecessary information for what they say is "contact tracing" (contact tracing was largely ditched a long time ago), in order to get our qr code (permission) to return home. Id like to see this challenged in court based on the same grounds the grounded kiwis took the government to court on (the right to return home). They won that case and it was deemed the government acted beyond their powers in only not supplying enough quarantine facilities to let kiwis come home.
