Large sunflower farm just an hour south of Auckland. $12 entry and picking sunflowers costs a little extra.
Note that blooming season is Jan/Feb!

Further information: The Taupiri Sunflower Farm offers a unique family-friendly experience located close to the motorway north of Hamilton. Visitors can explore the large field of sunflowers and take in the beautiful sights while picking their own flowers to take home. The story behind the farm is heart warming - the owners planted the sunflowers in 2020 to honor their late sister, and it has since proven to be a popular spot for visitors from all over New Zealand! Guests can wander through the small tracks surrounded by hundreds of sunflowers, or pick the perfect bloom for them, all while making the most of this colourful experience. There is also plenty of car parking available.
