Roger and Julie Corbett grew a 316g feijoa in Havelock North, which took the title from The Bay of Plenty Tree Croppers' 233g fruit.
Ms Tissink said she did not give the tree extra attention, and her family was surprised at the big fruit it produced: "It's a spindly tree. It's just a small feijoa tree that's magically grown these massive feijoas.
"I don't even water it. It just happened that way, it wasn't intentional. I'm not much of a gardener."
She said it was the first year the tree had grown such large feijoas and was surprised stories about the fruit had been so popular. The tree was about four years old.
Ms Tissink's daughter Rylee-Paige, 9, was a big feijoa fan, she said.
While she liked eating them raw, she was also a big fan of feijoa crumble.
Ms Tissink said she could make almost a whole feijoa crumble from one large feijoa.
Feijoa season typically runs from March to late June.
10 things to do with feijoas
Other than eating them as they are, Rotorua feijoa lovers are finding many other uses for them. We tell you how you can make your crop last until the next one.
1. Stew them
Slice 12 feijoas in half and scoop out the insides. Fill a pot with 2 cups of water and put on to the boil. Add a half cup of sugar (white or brown) and wait for it to dissolve. Add the fruit and simmer for about 10 minutes until fruit has softened. Stewed feijoas can be frozen in small containers or stored in preserving jars. Use in crumbles or serve with cereal.
2. Freeze them
Scoop out the flesh and freeze in whatever quantity you prefer. If you use fresh feijoas in baking freeze in the quantities required for your recipe to make baking a lot easier.
3. Dehydrate them
Skin, slice and dehydrate. Snack on them when out mountain biking or when at work. Visit http://feijoafeijoa.wordpress.com/2011/11/09/feijoa-fruit-leather-roll-ups/ for a recipe.
4. Bake them
Cakes, muffins, loaves. There are many different recipes for bringing feijoas to morning tea. Kiwi cook Allyson Gofton has a number of recipes, including these feijoa and lime muffins at http://www.allysongofton.co.nz/recipe/Feijoa-muffins-with-lime-glaze/. There are so many possibilities that you can get your friends together for a feijoa morning tea and each have something different to share.
5. Bottle them
In a large saucepan bring three cups of water and one cup of sugar to the boil. Peel 14-16 feijoas as lightly as possible and place into the hot syrup. Once all the fruit is added, bring to the boil for one minute. Using a slotted spoon, transfer the fruit to sterilised preserving jars. Pour in sufficient syrup to cover the fruit and spill over the top of the jars. Place the inner-seal lids on top and tightly screw on the seal bands immediately. The seal is complete once the inner seal is down and the feijoas can be turned upside-down without any syrup coming out. Once this happens the sealing bands can be removed. Wipe the jars clean with a damp cloth to remove any excess syrup. Store in a cool, dry place away from sunlight.
6. Make a salsa
You need: Three feijoas, peeled and finely chopped, one onion, peeled and finely chopped, one tablespoon finely-chopped fresh coriander, one tablespoon brown sugar, freshly ground black pepper. Mix all the ingredients together and serve with steak, fish, chicken or potato wedges, or great in rolls with cheese. Make an hour or two ahead for full flavour.
7. Drink them

You need: Six feijoas (scooped out flesh only), two handfuls of ice cubes, nine parts Bacardi White Rum, three parts Rose's Lime Cordial. Put all ingredients into a blender and mix until smooth, serve in a cocktail glass.
8. Preserve them
