Six matches are played with other District Associations, on a Home and Away format in alternate years.

Matches are played against the Hunter River, Central Coast and Lower North Coast Associations annually.

The Lower North Coast event is played for a shield named after Les Evitt who was a patron of the Association in the past, and the Hunter River match is played for the P.R. West Shield named after a past-President of the Association.

The match played against the Central Coast Association is for the Arthur Mollett Cup. Arthur Mollett was an official of the Brisbane Water Association and was the presenter of the Cup.

The NDGA also has an annual match for the David Wood Trophy which is played alternatively (every 2 years) against the Illawarra and ACT-Monaro DGA’s. 

The NDGA also holds a Schoolboys and Schoolgirls Championship.

The Association also runs a District Senior Pennant Series, a B Grade and C Grade Pennant Series and a Junior Pennant Series that are all very keenly contested. Each is run in two divisions.

At the completion of the Senior Pennant Series the Association's major annual dinner and presentation evening is held where all the Clubs and their supporters enjoy the pleasure of an evening out amongst all of their friends and fellow competitors. A separate annual dinner is held for the B and C Grade Pennant series.

The Districts main event is the District Championship. Players in the event must be members of a Club within the District Association to be eligible for the title. In conjunction with this Championship a Junior Championship is also held. The winner of this title must also be a member of a Club within the Association and must be under the age of 18 years on the date of the Championship.

One other important event run by the Association is Association Day. This event is held for the benefit of Golf Club directors and gives them an opportunity to play with directors from other Clubs. Games are generally arranged so that the players play with directors from other Clubs who have similar roles, i.e. Match committee, House committee, Presidents or Treasurers etc..., Secretary Managers and Greenkeepers of Clubs are also invited to take part. The day combines a pleasant outing with an enjoyable dinner and provides some reward for the time and effort spent by directors to promote golf.

The other major event held during the year is the District Mixed Foursomes Championship which is organised by the Newcastle-Hunter District Ladies Golf Association Inc. This event is fully supported by the Newcastle District Golf Association who provides sponsorship towards the event.
