"The Heartland XV games over the years have been exciting encounters and a great showcase for the stand-out players of the Heartland Championship. The three-match series will be a captivating finale to what has already been a stand-out Heartland Championship.
"It is also quite fitting that we take the Heartland XV to Samoa in the 50th year of Samoa's independence and the Friendship Treaty between New Zealand and Samoa.
"Samoa is a close Pacific neighbour and we share a great love for rugby, and a common pride in the Samoan players who have played their rugby in New Zealand."
