Namibia won the toss and put semi-final hopefuls New Zealand into bat in their T20 World Cup clash on Friday.
New Zealand are battling with Afghanistan and India for a last-four place with Group 2 winners Pakistan already through to the knock-out round.
The Black Caps are unchanged as they seek a third win of the Super 12 stage which would put the pressure back on to India who face Scotland later Friday.
Namibia, the lowest-ranked side at the tournament, have made two changes with Karl Birkenstock and Bernard Scholtz replacing Jan Frylinck and Ben Shikongo.
"The pitch looks good and small dimensions make it difficult to defend," said Namibia captain Gerhard Erasmus whose team have one win to their name after beating Scotland.
