I would love to have them too :). AFAIK no such free dataset exists.
You may ask at CODGiK [1] or GUGiK [2], 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 [3]:

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 [4]:

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.
