The hosts were in heaps of trouble early at 20 for two, with openers Hashim Amla and Morne van Wyk both departing cheaply.
It was a struggle throughout the innings as the batsmen battled to put partnerships together, demonstrated by the seventh-wicket stand of 54 between Behardien and Vernon Philander (30 not out) being the highest.
Pick of the bowlers for New Zealand was Doug Bracewell who claimed 3/31 from his 10 overs.
