Production has doubled since Psa. He's bought orchards and redeveloped.
''I am confident about the future, but if Psa has taught you anything, you hold it quite lightly. Before Psa everyone thought they were bulletproof, but we have been at the mercy of biosecurity, and that is a big challenge going forward,'' he said.
''Now I don't think any of us are under any illusion that there won't be another biosecurity threat.''
Hungerford said the family orchard was in the first red zone in 2010 and they had to cut out 12ha before the new G3 gold swap-out.
''We cut our gold out with no comeback really and nowhere to go, so it was a reasonably stressful time. We were used to cutting orchards; you might cut out and put graft gold on so it's something you are not completely unfamiliar with. But the thing was we had nothing to graft to it.''
He said the initial thought was to get in front of Psa.
''No one really knew where it was so you were effectively trying to stop other people's orchards getting infected. The early guys cut out to keep the rest of them going.''
Unfortunately, the Hungerfords' only option at the time was to graft to Sweet Green.
''We knew gold was toast, so that was really hard. A lot of us grafted to Zespri's Sweet Green which is now a failed variety, it was essentially uneconomic, so some of the early guys were really disadvantaged. Then we had to buy our way out over time, which cost a fair bit.''
But Hungerford remains passionate about the industry and is in it for the long haul.
''I think I'm reasonably good at kiwifruit and I like that it's quite a primal thing you do working with nature. You also provide quite a lot of jobs for workers and the returns off the land are essentially better than any other crop.''
