On February 10, Costco Australia and NZ managing director Patrick Noone said: "If all goes well, it will be a late August opening."
But this morning, a spokeswoman for the giant retailer said: "Unfortunately, at this time we cannot confirm an open date."
She said the 27-pump service station opposite the $100m-plus, size-of-two-football-fields Costco in Westgate would open ahead of the main store (or "warehouse" in Costco speak), but there was no timeframe. When the Herald drove by earlier this week, the self-service petrol station looked close to complete.
Since March 25, punters have been able to buy a $60 annual Costco membership from a temporary office - with in-person queuing the only option for the photo ID process.
On a local Facebook community group, people have complained about wait times of up to 90 minutes, with little or no enforcement of social distancing at times.
One person posted, "Please respect people's bubbles and don't just stand directly behind them, being close to someone isn't going to get you to be processed quicker just because you're closer to the till. I literally had someone breathing down my back despite having clearly marked socially distanced X stickers on the floor. You might not care about omicron anymore, but some of us would prefer not to catch it."
Noone responded, "Costco Wholesale takes the safety and security of its members and employees seriously."
He added, "Costco opened a temporary office on Kakano Rd in Westgate months ahead of our opening in order to start talking to the public and signing up members for their membership ahead of time in order to lessen rush and crowding closer to and during the opening week.
"We adhere to a strict Covid Safe Plan which we review daily to ensure we are conforming to government guidelines. We continue to welcome anyone with concerns, to speak with us so that we can investigate further."
His team was reviewing photos of non-distanced queuing shared on social media.
In its recent report into supermarket competition, the Commerce Commission said, "Woolworths NZ [owner of Countdown] also told us that Costco is seen as a "destination shop" and that they have seen analysis from Australia suggesting that Costco stores have in-person catchment areas of approximately 25km."
That's for general shopping. Across the Tasman, a report for the New South Wales state government found Costco influenced petrol prices in a 5km radius around its stores.
The AA says the Westgate Costco is likely apply downward pressure on petrol pricing in the area. Policy adviser Terry Collins expects opening specials.
The commission noted that while Costco was actively scouting for sites in Christchurch and Wellington, opening new locations would depend on the success of its first Auckland store - and would not impact competition beyond its immediate catchment area.
