Defending Wellington Sevens champions England beat Portugal 36-7 and Wales 21-7 with Dan Norton crossing for his 150th career try before they proved too strong for the current Series leader South Africa in a 19-5 win thanks to two tries from the Series' leading points scorer and England captain Tom Mitchell.
