I would love to have them too :). AFAIK no such free dataset exists.
You may ask at CODGiK  or GUGiK , if they have such data for sale
or who might; if they speak English.
At best I could find info like this on the CRS portal :
latitude limits of zones
zone I: 48°55' N ... 52°20' N
zone II: 51°20' N ... 54°30' N
zone III: 52°10' N ... 54°50' N
zone IV: 48°45' N ... 53°20' N
zone V: 49°20' N ... 51°20' N
longitude limits of zones
zone I: 18°00' E ... 24°10' E
zone II: 19°00' E ... 24°00' E
zone III: 14°05' E ... 20°00' E
zone IV: 14°15' E ... 19°05' E
zone V: 18°20' E ... 19°40' E
or in the EPSG database :
area_code= 1515 (Poland - zone I)
area_name= Poland - zone I
area_of_use= Poland - southeast - south of 52 deg 20 min North and east
of 18 deg East.
