To import the data from MapIt for South Africa, first download the
shapefiles from:

http://www.demarcation.org.za/index.php/downloads/boundary-data/boundary-data-main-files

Then create a new generation to import the data into:

    ./manage.py mapit_generation_create --desc "Initial import" --commit

Create the MapIt country, types and code types from a fixture:

    ./manage.py loaddata south_africa

Then try importing the data unpacked from the .rar files:

    ./manage.py mapit_za_import_boundaries \
        --wards=boundary-data/wards/Wards2011.shp \
        --locals=boundary-data/local-municipalities/LocalMunicipalities2011.shp \
        --districts=boundary-data/districts/DistrictMunicipalities2011.shp \
        --provinces=boundary-data/provinces/Province_New_SANeighbours.shp

If that looks OK, then add `--commit` to this command.

Export the police districts choosing 'Shapefile' as the format from:

    https://data.code4sa.org/Government/Police-Station-Boundaries/hr5e-pz98

Then import it with:

    ./manage.py mapit_import --commit \
        --generation_id=1 --country_code=Z --area_type_code=POL \
        --name_type_code=police --name_field=COMPNT_NM \
        boundary-data/police/Police_bounds.shp

Now commit that generation with:

    ./manage.py mapit_generation_activate --commit
