Many Kiwis on Reddit found the photo hilarious, with some sarcastically claiming that Pak'nSave "knew what they're doing".
Others said it reminded them of other crass advertisements they have seen across the country.
"Reminds me of the orange scaffolding utes I've seen around Palmy that say "Best erections in town", one person wrote,
Another added: "Reminds me of 'Sofa King good deals' — a play on the words "so f***ing good prices".
One American said they didn't understand what a ruck was.
"Imagine in a game of football where the guy with the ball in hand gets tackled and everyone piles in," a person answered.
A Foodstuffs spokesperson told the Herald that Pak'nSave liked to push boundaries in terms of creativity with their advertisements.
"The 'Sideline Supporters' campaign is national and customers can see it on TV, radio, online – the executions differ by channel and throughout the country.
"Regarding the placement of this particular poster, a quick shuffle to the left or right resolves the pole situation.
"Pak'nSave is well known for creating word of mouth with very little budget – feedback from customers is that they are enjoying being Sideline Supporters."
It's not the first time a Supermarket has fallen victim to a rather unfortunate gaffe
In 2018, visitors to the country were faced with a rather interesting welcome to New Zealand after Auckland Airport Countdown lost it's "O".
The store's sign appeared to have had the crucial letter missing for three days because of an electrical outage, before it was quickly fixed after the Herald reported the problem.
An image was posted to Instagram with the caption: "There's only one place I shop.
Also what people yell when I fall over. Ps @countdown_nz your sign has been broken for 3 days and long may it last."
