Owing to limited finances and a dearth of contacts with similar bodies overseas, New Zealand softballers have had very little experience of international competition. Since 1949, however, a New Zealand women's side toured Australia with considerable success. In 1954 a Victorian men's team toured New Zealand and, seven years later, this was followed by an Australian women's team. A New Zealand women's team toured Australia in 1964. During this tour the New Zealand team gained fourth place in the World Series at Melbourne. The association is now endeavouring to arrange for an American club team to visit New Zealand. The results of these various international tours are as follows:
| 1949 | New Zealand (women) in Australia: 3 tests, won 1, lost 2. |
| 1954 | Victoria (men) in New Zealand: no tests, 12 games, won 7, lost 5. |
| 1961 | Australia (women) in New Zealand: 3 tests, won 2, lost 1; 13 other games, won 12, lost 1. |
| 1964 | New Zealand (women) in Australia: no tests, 17 games, won 14, lost 3. |
| 1964 | New Zealand (women); World Series: 11 games, won 4, lost 7. |
