We need to hear back from petenunes. In the UK, it is spring, just like here. So, if the kiwis budded out last summer but lost their leaves and haven't grown back, they could be dead kiwi.
Just a couple clear-ups (I had a friend who was a kiwi farmer - the fuzzy kind). The skin of kiwi is edible but wash off the fuzz. Unless you are out walking the length of the row, then rub it off and eat away.
Another friend and I both got kiwis from our local nursery. But... friend #2 ended up with two female plants. I was luckier and had one of each. The flowers are quite different - its easy to tell them apart. I tried for years to root a male plant from cuttings but never succeeded (the female rooted by herself, where ever a vine touched the ground).
But, even without a pollinator, Friend #2 had kiwis. They weren't big and plump but she did get kiwis without a pollinator. The years we got our acts together and I took her a blooming branch from my male plant, she got plump kiwis. What we learned is that the more seeds a kiwifruit has, the bigger the fruit. So no pollinator, no seeds, tiny fruit.
Kiwi vines are incredibly heavy. I planted mine on a peeler core fence with wire and it took down the whole fence. Luckily, the kiwi was big enough to partially hold itself up and it also climbed a near by eucalyptus tree. After climbing the tree, it rooted in the creek. You should have seen how big those kiwi were then.
