The merging of the neighbouring Royal Auckland and Grange Golf Club's was formalised in 2014, when members voted to join forces and consolidate their two courses into one new 27-hole Nicklaus Design layout. Royal Auckland's history dates back as far as 1894, and the Grange to 1924. The value of surplus land has enabled the new club to pursue what from the outside seems a rather ambitious project - of using a modern Nicklaus Design as a means of establishing a new entity as an exclusive, unique private club facility. The course is expected to be completed by 2021.

The club's website describes the Future Course as below:

The new layout will spread equally across the Grange and Middlemore properties. Two bridges will link the properties across the estuary, one for golfers arriving to the Clubhouse and another to ferry them across the estuary as they play the course. The club will also boast a brand-new Andrew Patterson designed clubhouse as well as a 300- metre driving range and short game practice facilities. The new entity, the “Royal Auckland and Grange Golf Club” will be comparable with the best metropolitan clubs in Australasia.

The project will be carried out in two phases, the first being the construction of the 13 holes on the Grange property, the bridges and clubhouse. These elements will be completed in early 2019. Phase two will see the balance of the holes constructed on the Middlemore property, along with the driving range, all to be complete in early 2021.
