Gusto was their calling card. Some of their defensive work was little short of heroic, but their line was leaking well before the end.
They had their moments. Flanker Tinus du Plessis was first to a loose ball and charged 45m up the middle without a hand laid on him; just before halftime quick hands had South Africa's defence hustling back.
But Namibia could not buy a trick from referee George Clancy.
His penalty count was 9-1 late in the first half in favour of the Springboks.
Their coaches were after accuracy and improvement out of this game, steps forward from the Fijian win last Saturday night in Wellington.
Keeping the foot down for the 80 minutes would be a good sign of intent, and they did - seven tries in a 19-minute burst late on proof of that.
It wasn't perfect by any stretch but there were plenty of quality moments, too.
Bryan Habana's try midway through the first half made him South Africa's top test tryscorer with 39, and it was his first since June last year; Morne Steyn ran - enough said - and gave his repertoire of kicks long and short a workout and kicked for goal at 100 per cent; at times there was pace and penetration to impress; and the pack flexed their collective muscles with a pushover penalty try.
A rousing, if one-sided night, but on that score there would be few complaints from this particular home crowd.
