Namibia captain Gerhard Erasmus felt that his bowlers were unable to carry on the good work done until the 16th over which led to their Friday's T20 World Cup match against New Zealand.
New Zealand were struggling at 87/4 after 14 overs but smashed 73 runs off the last five overs to post a total of 163 in 20 overs.
"I thought we bowled well for a while, probably for the first 15-16 overs, but the death overs didn't go according to the plan. We need to go back and make plans for the death overs," Erasmus said at the post match presentation.
"It's all about using the right bowler at the right time towards the end. We got one more game so we need to try and nail that aspect, so hoping to do that against India.
"It was quite a tough pitch though. 160 was a bit too much on that wicket. As I said it got away from us towards the end," he added.
The Black Caps restricted Namibia to 111/7 as they went second in the group points table. Despite a scraping through, skipper Kane Williamson was glad that his team was able to up their game when needed.
"I think we all know what we have to expect here, it was a real scrape. We tried to maximise that short side, it was a challenging surface. The guys played well to get us 160. An over or two can crack the game, that was our focus," he said.
New Zealand need to win their final group match against Afghanistan in order to progress to the semifinals .
"They are a strong side and they (Afghanistan) have played good cricket, they have some match winners. Looking forward to that challenge."
Jimmy Neesham was adjudged the player of the match for his all-round performance as scored 35 not out off 23 balls and claimed 1-6 with the ball.
"It was a two-paced wicket, there were talks about the repercussions if we had lost today, but we were not thinking about the wicket," Neesham said.
"We needed to do well and the key for us was to set a par total, the way we went out there and played on a challenging surface, I'm pleased with it."
