Captain Assad Vala finished unbeaten on 144 with John Reva adding a valuable 45 runs down the order.
The Namibian innings got off to a disastrous start, losing two wickets in the first four overs, and the visitors went into the lunch break 38 for 5.
Visiting captain Sarel Burger went some way to stabilising the innings, compiling a hard fought half century.
He ended 52 not out as the Africans were dismissed for 146, with Lega Siaka and Norman Vanua picking up three wickets each.
The second day was cut short because of showers with PNG four without loss in their second turn at bat, a lead of 169 runs.
