No quite. The 'inbetween' the more transitional it is. So SC in the states would be more transitional than New York city. Orlando would still be transitional but more sub/tropical than Washington DC but would go under the transitional 'umbrella'.
But keeping in mind the two subtypes cool/cold winter and warm winter.

So now there are no set rules, other than the "inbetween" rule?
South Carolina is more transitional than NYC - really?
Places in the lower end of the zone are much more debatable. From my subjective view, the "most" subtropical would be the climate most evocative of year round warmth. I would say that here is warmer over the year than somewhere like NYC. The far greater heat of a New York summer doesn't compensate for the colder winter and adjoining months.
You might be right about NYC, but I took a look at a comparison between Nelson and Washington, DC.
Washington is warmer than Nelson for 7 months of the year. The summer avg temp diff between the two is a very large 15F, while the winter diff is a lot smaller and is 7.4F.
The year round mean for DC is 58.2 vs 54.7 for Nelson.
Nelson is only warmer in the three winter months, and one Spring month (March vs September).
DC is warmer the rest of the year, except for a tie in the 3rd Autumn month (50.1 Nelson vs 49.6F DC).
Even here in Philadelphia we average 6 months warmer, with one additional month very close (2nd Spring month 54.4F Nelson vs 54.0 Philadelphia).
So really, it is not just the summer that is warmer but extends beyond the summer, particularly for DC.
I'm not saying that DC is subtropical and Nelson isn't. Nelson can grow more subtropicals due to the lack of winter frigid cold. I just think it is inaccurate to say New Zealand is warmer except for summer.
If our winter std deviation was as low as Nelson, DC could grow a lot more vegetation. It is the deep swings in winter which would kill tender vegetation. Your avg low is in the mid 30'sF in that part of NZ, but the winter temps don't usually go below 23F. Around a diff of 13F.
In DC, the avg winter extreme winter minimum at Reagan National Airport is around 10F. In 2008 it went down to 8F. That is 21F below the mean Jan low of 29F. That one extreme night each winter would kill off the veg that can grow in Nelson and doesn't get killed off. Also, colder daytime temps or ice days due to the high std deviation would be more frequent. This prevents a lot of subtropicals.
We can just get much colder in the winter.
Venice, Italy has Jan avg's of 42/30.4F, just about the same as DC. Yet, you will not see a scene like this in DC. I doubt you would even see a scene like that in Norfolk, VA or the Outer Banks of NC.
All because of the wild swings in winter temps.

Really? I'm sure all those plants can grow in Norfolk, VA and Outer Banks of NC. That looks almost like a neighbourhood you can find here in Vancouver.
Looks similar to this house in Leeds - Google has recently updated Streetview, they were there before, so they've clearly survived 1 chilly winter and 2 very cold winters. Surely they must be able to grow en masse in the Outer Banks.
