Preheat oven to 180°C. Grease a 22cm square baking pan and line the base and sides with baking paper.
Sift flour, baking powder and ginger into a bowl and mix to combine. Place butter and Pua-ā-Tāne Wild Forest Honey in the bowl of a stand mixer with the paddle attachment and beat until thick. Fold in the flour mixture until well combined. Press mixture firmly into prepared pan and prick all over with a fork. Bake for 25-30 minutes until light golden.
Meanwhile, for the ginger icing, place the butter, honey, icing sugar and ginger in a medium saucepan over low heat. Cook, stirring, for 3 minutes or until butter has melted. Pour ginger icing over the cooked base while both are still hot and set aside to cool completely.
Once fully cool, using a hot knife, cut slice into 16 squares to serve.
