The things that Mr and Mrs Gock help with in new zealand ?

What did they contribute to new Zealand 
Mr and Mrs Gock helped New Zealand in many ways and they were helping New Zealand by keeping our fruit and vegetables fresh. How they helped keep our vegetables and fruit fresh with the broccoli if you were to pick a broccoli out of the ground it would turn yellow but they found a way to keep it green and fresh there way of doing that was butting it n a chilly bit with ice and that's why you see broccoli in a freezer when you go shopping. With the fruit they put stickers on the fruit 
 If the sticker has a five-digit number beginning with 9, it means that your fruit was grown organically and is best for consumption. How Did the Stickers Come About? It's the International Federation for Produce Standards that gives out the stickers all across the world; it enables standardizing of the process.
