Henry notched his second wicket in his next over when he removed Rilee Rossouw for a duck, clinging on to a return catch to leave the tourists 40-2.
AB de Villiers arrived at the crease and along with De Kock began to take the attack to the Kiwis' bowlers. The duo moved South Africa past the 100-run mark as De Kock began to take charge and he brought up his 50 off 67 deliveries.
Their 50 partnership arrived in just 46 balls as De Kock began to find the boundary with ease and moved the score past 150 in the 30th over, looking well poised for a century on 80 not out.
However, the rain came down and stopped the innings. The weather proved to be too intense for the match to continue and as a result the game was abandoned.
