But when it comes to participating in sport or recreation in man-made settings - including swimming pools, gymnasiums, stadia and sportsgrounds - only 72 per cent of those who do participate in sport and recreation in the region do so, compared to a national average of 91 per cent.
Mr Eastwood said this showed that Northlanders were taking full advantage of our natural resources, such as waterways, oceans, beaches, bush and their backyards to participate.
"[The figures] are great and show that a lot of us are participating, but they also show there is some work to do," he said.
"More people here are accessing our natural environment to participate in sport and recreation. But our challenge is getting more people to do that, to increase our activity levels and therefore increase the health of our population."
He said there were many advantages to getting healthier and more active.
Mr Eastwood said if more people are exercising and healthy some of Northland's poor health statistics - including high levels of diabetes, obesity and heart disease - can be overturned, which means savings for the health system. Being healthier also made people feel better about themselves.
Sport and Recreation Minister Jonathan Coleman said the report provided a useful snapshot of Northland's sport and recreation sector.
"The reports help to highlight the challenges and opportunities for Northland's sport and recreation sector," Dr Coleman said.
"While these figures are encouraging, there's room for improvement. People in Northland are not immune to the global drift towards an increasingly sedentary lifestyle."
The report shows that the sector contributes just over $84.5 million, or 1.6 per cent, of the region's GDP and employs 1284 people.
