The Supreme Award for a Boutique Manufacturer was awarded to Puhoi Valley Cafe, which won with their Chai Latte Ice Cream.

The largest number of entries came from sorbet with 60 entries, premium ice cream with 53 entries and gelato with 44 entries.
A new non-dairy category was added to reflected the growth in the industry.
Kohu Road Ltd took the top spot in non-dairy for its Kohu Road dairy-free strawberry flavour.

The judges selected Matakana Roasted Affogato Yoghurt Ice Cream made by Puhoi Valley Cafe as the winner of the category.
The winner in the Kids Choice category was very predictable - Candy Floss and Marshmallow Ice Cream by Puhoi Valley Cafe.
A dozen students from Westmere School in Auckland judged 15 different ice creams.
