My mother is the same - heat pump runs almost all-year-round to cool her house.
A proper heat pump would be the best option. Do you have one in the house currently?
I have one at each end of our house - one in the lounge and one in the master bedroom.
During a hot 26 degree day, both must run to cool the house but at night we only need the lounge one going and i cant hear it from my bedroom. So maybe this is a reason to get a heat pump installed in the lounge.
Portable air conditioners are not good long term because they consume a lot of power and dont cool a large area but may work for this situation. They are also very loud.
Maybe you can hire or borrow one?
I truly believe single hose units should be illegal to sell in NZ. Delonghi used to sell a dual-hose model but it was about $200 more expensive, didnt sell well due to price, and so they stopped bringing them in. But it worked so much better than a single hose model.
Your concern about the window is valid - they only ever come with sliding window kits.
However when I was working in a temporary portacom office with pivoting windows, I cut out some large cardboard flat sheets, glued them together for thickness and rigidity.
Jammed them in the window to seal it and then cut a hole for the hose to go through and keep a tight seal.
In another temporary office, we had one set up so that it was out in the garage, using garage air as the source and waste, then had a baffle to direct the cold output into the office so it was only creating positive air pressure in the office with cold air going in.
Edit: I have seen a couple of camping portable air conditioners that may work - they seem to come with dual hoses.

Edit: Ecoflow i thought was the one - but it only has a single hose.
I see jaycar has a model, will check that for you.

It appears jaycar sell the only dual hose model in NZ.
Its not very powerful - only does a single room.
But at 240 watts, it would be a lot more efficient in how much cooling it can do with balanced air pressure compared to an 800 watt single-hose portable air conditioner that creates negative air pressure in the room.
Being that its designed for tents and camping, its not going to come with a great window kit but you'll have to make something out of wood/cardboard anyway for that.
another idea...1min....
Trade Depot search their site for Window Kit
They sell window kits for push/pull pivot windows which i think would work well. You would need to cut a second hole for the second hose.
This diagram should explain why portable air conditioners with a single exhaust hose are bad.

DeLonghi. They perform better and are quieter than the budget models.
In the mega summer I got an ElectriQ standalone one. And it did get out 40 degree office down to 25c, but it’s louder than a jet taking off and still not “cold”.
A friend has the equivalent DeLonghi and it’s quieter and much cooler. I should have gone with them.
We moved house and got a proper split system in our loft conversion and it’s WAY better. The nighttime indoor quiet mode is amazing and we just pop a fan at the top of the stairs when it is really hot to blow cool air downstairs.
It heats and air purifies too.
I live in an old for the PNW house with windows redone in the 1970s and have to do portable units. The inverter units are the best but the best portable is nowhere near as good as a mediocre window AC. Some of the Frederich models interest me because you can still manually dump the water which really offloads the compressor versus having to burn off the water in the exhaust. If you can window, if you can’t double check consumer reports and wirecutter. I have been okay with the Delonghi. Woot.com sometimes has amazing deals on ACs.
check the decibel levels before buying…a lot of portable ACs are advertised as quiet but still hum loudly. I ended up with a DeLonghi and it’s been great so far
Got an Electriq one too that gets dragged out of the garage every year for a few weeks. Been going for about 6 or 7 years now. It is noisy, and heavy, but it cools our lounge down nicely. I cut some cardboard strips to stick in the gap in the sliding patio doors above the hose, and just pull a curtain across to hide them.
Had a Penguino for a few years but then it lost its gas, and despite phoning loads of companies it didn't seem to be refillable/repairable unless someone cut the system open and brazed in a valve or something apparently. When it worked it was good though...
