Golf visitors fell into two categories, those who come here for a holiday and play a round and those who come specifically to play and have a holiday on top.
Watson said Tourism NZ would target the second category.
They travelled throughout the country and spent on commercial accommodation.
Most came from Australia, the United States and Asia - specifically China - and these countries would be the target of the campaign.
Marquee courses including Kauri Cliffs in Northland, Cape Kidnappers in Hawkes Bay, The Hills at Arrowtown, and Jack's Point in Queenstown, were popular as was the next tier down.
"A lot of places in the world have good golf courses but what New Zealand has to offer is not only the environment that they are set in, but also the amazing breadth and accessibility of other courses."
Watson said there were about five million potential golf tourists in the target markets. A working group led by golfer Greg Turner would formulate a long-term strategy which would include promotion overseas - perhaps using an international golfer - but also look to ensure courses are geared up sufficiently.
