New Zealand regularly uses flying companies to take aerial imagery photos of most of the country, which is generally taken between 30cm and ~2cm, Land Information New Zealand (LINZ) then releases this imagery imagery completely free (CC-BY)[1,2] to the public and can be downloaded as GeoTIFFs [3]

I think LINZ decided that <0.05m might have some privacy issues due to being able to distinguish people in it, and have held back releasing some <0.05m or they may have reduced the quality of it.
