Sounds like the AT220: https://nzautotraps.com/

The use of photoeyes (infra-red beam) on the one that can do mice seems dangerous for non-targets.

Looks promising otherwise - I see several potential issues that might be exposed quickly such as the radius of the corners of the enclosure being to sharp - needs to be a smoother radius too prevent rats chewing them open (smoother than a rats mouth gape can grab onto). A rat/several rats could get into it and destroy the wiring very quickly.
The pull type trigger might be a barrier to efficient control of rats as it can be variable whether they will do this. While the AT220 doesn't seem to be targeted for the stoats I would be as bold to say that they would not set off such a trigger. Bait life will also be an issue - I've informally tested "long-life" baits that are supposed to last for months that have no smell after days - Suspicious at best on their long-term efficacy.

Some learnings from the Goodnature A12 and A24 traps (CO2 self resetting possums and rat/stoat traps) could be transferred to speed up development it seems.

Interesting trap alright but looks a bit chunky at the moment to lug around the hills?

Having used the Good Nature A12 with 16g canister - bit of a rip off really - they retail for about $185.00. And quote up to 12 possums from one 16g canister, charging about $7.00 per co2 canister. So the A12 and A24 traps have ongoing costs with lure, counter etc, not just a one off in buying them. I have now sourced other 16g canisters at half the GN cost and even sourced a 25g canister that i expect to get more than 12 activations to make it last longer in the hills. Personally though the GN traps are well designed i think the high cost for ongoing use is a bit over the top - hence only a Govt Dept like DOC would buy them in bulk. What do DOC do with the thousands of empty co2 canisters - can't be refilled with the top pierced. Recycled, yeah nah. Can't beat a whole lot of gin traps laid out and fur in return.
