If we call 34/12 humid then it doesn't leave many other words to describe conditions like 34/26 like they get routinely in equatorial regions.
I also thought that Queenslanders wouldn't find 19C or 20C dewpoints particularly humid.
It is all relative, people from Dunedin would certainly call it humid
I noticed the locals in Noosa were complaining about the heat that day, I certainly noticed it.

I have walked around Dubai when its humid there (and hot)
its weird how they have all that humidity coming from the Indian Ocean/Persian Gulf and yet it is a Desert region
(while we were there we did get some rain from a high based cloud sheet that moved over...similar to what Queensland can get , i,e jet stream associated cloud that has moved across the interior but has picked up moisture the closer it gets to the coast line..sort of thing

I grew up in Auckland, hearing Merv Smith on 1ZB giving the weather forecast each day including the expected temperature and
percentage of humidity.
The higher the percentage, the more one knew to expect a muggy or clammy day, uncomfortable, one needed a fan running as open windows wouldn't help cool the house down; not so great for getting laundry dry.
I've never got the hang of dewpoints: picturing moisture forming on a cold glass of something doesn't seem very useful

but in the morning the relative humidity is higher...because the temperature is lower (and closer to the dew point) anyway
but it is all relative..i,e a relatively high RH in the morning , will indicate a high underlying dew point

You can't beat good old grams of water per cubic metre of dry air. Oh, wait...

Comprehension of RH is very limited amongst non weather enthusiasts in my experience. I wonder if an index relative to a fixed temperature would be easiest to understand? E.g. take the highest dewpoint that's ever expected to occur in NZ in a 10 year period. About 24C? Then define the humidty index to be "what the RH would be if the temperature was 24C". Less useful at low temperatures, granted.

Nice day to end off Spring. Cloudy and gloomy with some drizzle this afternoon. Had to light the fire

We had 6mm of rain in Rangiora with some kind of convergence stuck over us.

A generally mild November overall. Notably dry in Gisborne and Hawke's Bay, but relatively wet in central NZ and Otago. Fairly sunny in the north and east of the North Island, but mostly cloudy elsewhere.

Here's NIWA's preliminary, '
November 2016 National Climate Summary'.
A wet and cloudy month for many.
The national average temp of 14.1C was 0.4C above normal.
Gisborne recorded 34.8C on the 23rd - 2nd only to a dodgy-looking 37.1C at Waiau in 1985 as NZ's highest ever November temp.
The month's lowest temp of -1.5C was recorded at Hanmer Forest on the 1st.
It was also Wellington's wettest November on record.

A disturbed westerly pattern for Nov rather than the more typical southwesterly pattern.

If older Wgton city cites are included, the only wetter November was in 1875.
The low record for "Paraparaumu" sunshine meanw little as there are 3 sites in the area - the manual Aero one whose numbers look OK, the Aero AWS which always looks too high (even allowing for EWS status), and now a town EWS which looks very low, probably a poor exposure.

Surely Riccarton was higher ?

^ NIWA's Riccarton HQ recorded 31.0C on the 23rd (Chch Aero 28.4C, Rangiora 29.4C, Cheviot 30.5C).
