hmmmm - I had previously posted about the door to the Freezer room being left open - and - yup; you guessed it - once that happens then it gets cold in good ol' New Zealand.
In case you missed it - the ol' dude up there had a ball when he separated Light from Darkness and water from soil and so forth!! He created Earth and everything that is in it - or better on it!!
Our little paradise New Zealand - is often called Godzone (or phonetic as I think of 'Gods-own')! If you think about it - it has literally everything you can find elsewhere on the planet. Fjords / Sandy Deserts / Rain forests / Alpine regions / Flat plateaus/ long deep cave systems/ braided rivers to stunning narrow gorges/ Glaciers that retreat and grow (long-term weather depending), a Lake district, Geothermal activity (speak mudpools and geysers Ala Yellowstone Nat. park), stunning white (AND Black) sandy beaches - some so remote you can sit there all day long and be a hermit, natural hot mineral rich clear water springs, and yes - some very large powerful earthquakes etc.
In terms of weather you can have every possible scenario - from month long droughts to monsoon type of rain, from heat-waves to snow - blizzards, crazy Foehn-type winds (with wind speeds from 110 - 300km/hr) vs long days of calm. At any given day you can go from hot Fan-bake (+30c) to ice cold-snap freeze (5c) in less then an hour! Houses used to be built on piles for the simple reason that anywhere - anytime, some 100-150 mm of rain falling inside 10 hours can happen.
The above picture is from windy.com and as you can see - the air comes of the big chiller room aiming straight at NZ!! Luckily for those further north - by the time it gets past the central plateau it will have sufficiently warmed up, to the point where we call anyone living north of Auckland - "living in the the winter-less north".
PS - did you notice the MINUS 63 Celsius in Antarctica???? :P
That cold air-mass can reach Brisbane (warming itself from the Tasman Sea) cooling them down to a "BALMY" 15 C !! It never reaches much further north - and we have friends in Darwin who say it is 30C year round - they just have a dry vs wet season!!! Ooooooh; to live in the Cook Islands where is a balmy 24 during a COLD day!!! :)
Anyhow - If you think you can design a landmass that can outdo NZ - feel free to get creative! I happen to think that the Ol' Dude up there out-did himself and had a bit of fun with NZ and he just made it -- perfect!!
