Mr Walton has been working in Whanganui for the last year. He has also worked a lot overseas, but said he always spent time at his bush block when he was in New Zealand.
The log cabin there, Mt Hiwi Lodge, is 20 years old and sometimes available for rent.
It's also used by his conservation-minded neighbours, members of the Mt Hiwi Charitable Trust.
Secretary Richard Lucy said the group of six to 12 owned 400ha of forest with high conservation values at the head of the Moumahaki Stream and lakes in Omahina Rd. Members bought it in 2001, from political hopeful Terry Heffernan.
He wanted them to carry out his conservation goals, and progressively reduced the initial price of $79,000. The Nature Heritage Fund finished the payment, putting in about $50,000.
The land is "vicious country", very steep, and some of it has never been logged. It has kiwi, and also short- and long-tailed native bats.
The trust members were initially from Taranaki, but most now live elsewhere. Mr Lucy said they tried to get to Mt Hiwi every month or two to trap predators, and they also wanted to fence stock out of the land. They encourage hunting, to keep goat and possum numbers down.
They want to join with other nearby landowners to keep 1000ha predator-free, making a viable breeding area for kiwi.
The trust land is open to the public, but trust members need to know when people are there, in case hunters are also working. Mr Lucy can be contacted on 027 249 4255.
