import geopandas as gpd
from geoarrow.rust.compute import area

path = "/Users/kyle/Downloads/nz-building-outlines.parquet"
table = gpd.read_parquet(path)
gs = table.geometry
area(gs.to_arrow())

Now gives an error of

Exception: General error: Expected GeoArrow native type, got 'geoarrow.wkb'.
If you're passing a serialized GeoArrow type like 'geoarrow.wkb' or 'geoarrow.wkt', you need to parse to a native representation.
