The 2017 World Masters Games added $63 million to the country, around 18 percent more than the original target.
The target of $52m was surpassed, making the Government's $11m investment, along with Auckland Tourism Events and Economic Development's $11.75m, worthwhile.
There were 28 sports played across 48 venues with more than 28,000 participants, and the games took four years to plan.
Economic Development Minister Simon Bridges and Sport and Recreation Minister Jonathan Coleman say the games were a great success, and a testament to the hard work put in.
"The 'sport for all' philosophy of the games was highlighted by the age range of those attending. The average age of the competing athlete was 54 years with 25 years and 101 years being the youngest and oldest athlete respectively," they said.
