The move higher was driven in large part by gains in Toronto, Oshawa, Ont., and Vancouver.
The combined region of Toronto and Oshawa was up 0.2 per cent due to higher material and labour costs as well as market conditions.
Vancouver posted its largest gain since March 2010, climbing 0.6 per cent.
Charlottetown reported the largest increase at 1.0 per cent, due to market conditions and higher land development costs.
On a year-over-year basis, the new housing price index was up 1.1 per cent in April, the smallest annual increase since February 2010.
