The range was impressive, with some rings selling for more than $19,800.
The clothing section came next - filled with brands like Puma, Fila, Calvin Klein and Tommy Hilfiger - before shelves of kids' toys and barbecues.
Finally, the food aisles and everything was just BIGGER.
Brie cheese at least three times the usual size for $13, 1.6kg buckets of hummus and giant bags of potato chips.
The fresh produce section is probably the most highly-anticipated by Kiwis amid our current fruit and vegetable prices.
For the past 12-month period, grocery food prices increased 7.6 per cent - fruit and vegetable prices rose 4.9 per cent alone, the largest contributor to the monthly rise.
While it was difficult to compare prices in Australian dollars and many of the fruit and vegetables locally imported, bulk buying was again the trend.
Some fruit such as apples were able to be bought individually, but most produce was sold in larger amounts in a bid to keep prices low.
The rest of the store had some surprising additions such as a tyre centre, optometrist and hearing aid centre.
And to help you follow the age-old advice of not shopping when you're hungry, every store has a food court offering pizza, burgers, drinks, sundaes and their classic hotdog combo which has famously stayed priced at under $2 since the 1980s.
While each Costco varies slightly, offering a mix of imported and locally sourced items tailored to its location, New Zealand's warehouse is set to have plenty on offer for Kiwis.
Memberships cost $60 a year and are available to purchase now.
