Pakiri Beach Holiday Park manager Rachel Macfarlane said her business was one of many in Northland that benefited from people walking the trail.
More than 200 walkers had made overnight stays at the holiday park on the Matakana Coast, this season, making a positive contribution to her business and others.
"It's really cool when they come through because a lot of them slot in around the traditional busy season. Those heading south often arrive in spring and many the walkers walking north arrive in autumn," she said.
Many bought supplies at the park shop before continuing their journey, and the diversity of visitors from overseas and other parts of New Zealand created a lot of energy and goodwill, she added.
Many local authorities are also positive about the trail's impact. Palmerston North City Council leisure assets officer Brian Way said Te Araroa walkers had been "very visible" in the city over the past year, particularly along the Manawatū River Pathway and in the town square.
"Te Araroa helps put Palmerston North on the tourist map," he said.
"Walkers provide an opportunity for locals to meet people from other countries, and they all stay somewhere and have to eat, so our supermarkets, restaurants, outdoor stores and accommodation providers all benefit."
Mr Weatherall said the economic benefits provided by trail walkers were just one facet of what Te Araroa was contributing to New Zealand. It also provided physical and mental health benefits for walkers, built a passion for the outdoors among children and young people, and connected Kiwis and others walking the trail with the people and landscapes that made up New Zealand.
The challenge for the trust in future was to ensure the growing number of visitors were managed for the benefit of trail walkers, as well as the environment, businesses and communities it touched.
"We know the trail's popularity places pressure on infrastructure, so one of our major focuses in future will be on working with local and central government agencies, iwi, private landholders and others to ensure future growth in walker numbers is managed effectively," he said.
The trust was working on a new strategy that would prioritise the trail walking experience, along with the sustainability of the trail and the environments and communities that supported it. That strategy would be available on the trust's website in the coming weeks.
