When you pop up the rear hatch there are two plastic trays at the rear near the tail lights. The holes in these can get plugged up with stuff. In my area it is hemlock tree needles. If those holes are plugged and can't drain the water that comes in through the gap between the hatch and fender, the water can overflow into the trunk area during a hard rain.
If it a different kind of car same idea, look for where the water/rain should be draining from the gap between the lid and the rear fenders.

This might not be your exact problem, but there are further links contained within which might prove helpful for testing or research. You might want to spend some time searching the site for additional threads/links as well.
Typical leak points for standing hatch water seem to be related to the glass seal (near the spoiler), the tail light panel, or issues with the drainage holes at the back of the hatch channels (as mentioned above). There are other areas where/ways in which the hatch can also leak, but these usually result in water standing on the rear floor pan.
