Just that New Zealand's environment has been rendered unique more because of geologic history than by climate. Nothing to do with it being subtropical or not.
To put it another way, New Zealand's geologic history is very distinct from NW Europe whereas their climates share a lot of features.

That's pretty obvious, but that's pretty true the world over. All environments are unique.
Features are different to climate though - hence my point about exotic plants. How many jacarandas are there likely to be in Amsterdam?
This thread is a continuation of the discussion in the recent thread Climate cities in the same classification but very distinct in nature? , i.e. Climate cities in the same classification but very distinct in nature?. In the thread many posters objected to the broad classification of Koppen's Cfb climate. Below I will suggest some possible changes to this.
I propose an distinction between different kinds of oceanic climates as follows:
No. of months 13'C or above:
7 or above - Warm oceanic climate (Annual average must be below 17'C)
5-6 - Typical oceanic climate
3-4 - Cool oceanic climate
0-2 - Subpolar oceanic climate (Annual average must be 5'C or above)
If the climate has one or more months with a monthly average of 1'C or lower, it is considered a semi-continental oceanic climate. What do you think?
No. of months 13'C or above:
7 or above - Warm oceanic climate (Hottest month must be below 22'C, annual average below 17'C)
5-6 - Typical oceanic climate
3-4 - Cool oceanic climate
0-2 - Subpolar oceanic climate (Annual average must be 7.5'C or below, winter month above theresold*)
The theresold is W = 3 - 0.4T, where W'C is the minimum winter tempeature and T'C the tempeature of the hottest month.
That's pretty obvious, but that's pretty true the world over. All environments are unique.

Amsterdam is at latitude 52°N though so that's not really a fair comparison. Do you think somewhere 200 km south of the Auckland Islands could grow jacarandas?

Actually due to island heat London fits into the transitional temperate/subtropical category (Tm>10ºC), but its surroundings (the typical England's countryside) do fit into the C3to, because they fulfil the main requeriments of a Temperate climate (C3t), wich are annual mean btw 3ºC and 10ºC and Pp above 250mm. But then i proposed the subdivisions Temperate continental (C3tc) and Temperate oceanic (C3to), both with their respective requeriments (the latter's mentioned in my previous post). And the one among the two sharing more fulfiled requeriments with a given place, is the actual climate of that place.
The typical southern English countryside has means above 10c, summers are above 15c for pretty much the entire country, and below 1000mm, so that still wouldn't fit.
I think there's two major types of Cfb climates: those that are considered subtropical and those that are considered temperate by the Trewartha classification.
Cfb climates with >7 months with an average temperature above 10°C = Subtropical
Cfb climates with 4-7 months with an average temperature above 10°C = Temperate
