I think you've covered it already, but there must be still camera options now that do good quality video? I realise it's expensive to upgrade camera and housing, but if you're going to blow NZ$1K on a GoPro or whatever, that would be some saving.
Maybe you need both
I'm a bit behind the times, so wasn't aware that these existed. Hopefully, they do both jobs well.
I see a franken spider pyramid imaging system in your future: a GoPro on top of the TG7 ON TOP of the Olympus, plus two strob
Unless you're going to buy a decent lighting setup or stay shallow with lots of sunlight, I think you'll be disappointed with the output of both cameras. Beyond that, you may get frustrated with the lack on manual controls on the GoPro. Not sure what the TG7 has in this respect, but I suspect more options. Benefit of the GoPro is that you can mount it on your main camera rig via a hot shoe and it's not too big. Also, they shoot in fisheye/wide angle which is great for underwater work, at least for subjects that you can get close to.
GoPro macro is a huge pain in the arse. It can be done, I've done it, but the fixed focus length makes it challenging.
I had an Olympus M4/3 camera for stills and the video output was shocking. May as well have used a potato!
