I wouldn't call it wget friendly but I had success with the following cli

wget -nH -nc -O $HOME/miniZ_v1.8y3_linux-x64.tar.gz "https://miniz.ch/?smd_process_download=1&download_id=4368"

You have to get the tarball name and check the download_id which you can find when you hover over the download link (it show left-bottom with firefox)

Hope this helps.
