The 15th of October to the 26th of February. That's the period during which the angle of the noon-day sun in Rotterdam never reaches 29.7 degrees, which is the zenith angle of the sun on the shortest day of the year in Auckland. That whole four-plus-month period, in terms of solar efficacy, never exists in Auckland.
This photo of long shadows at midday, the sun struggling to make 20 degrees in November, can't be taken there. Which makes me wonder if
this photo, from the second-shortest day of the year and in which I look like I've been punched in the face, couldn't be taken there either. Just a thought.
(And, a quick go at the New Zealand immigration points checker suggests I get enough to be able to just move there, regardless of whether I've got a job lined up. Also a thought.)
