It is also the fourth consecutive year the discount supermarket chain has received a five star rating from the Australian public for offering value for money.
Of the other supermarkets mentioned in the study, Foodland received five star ratings for quality of products, customer service and accessibility of staff, layout of store, and freshness of fruit, vegetables and meat.
Coles earned top marks for quality of products, range of products, customer service and accessibility of staff, and layout of stores, and Woolworths saw five star ratings for range of products and layout of stores.
The Canstar Blue survey, of 2500 Australian adults, shows that 53 per cent are loyal to their supermarket.
Of those, 66 per cent cited familiarity with the store as the main reason for their loyalty, while 56 per cent said it was closest to their home and 53 per cent said they have a loyalty card and enjoy collecting reward points for their loyalty.
About a third of respondents (35 per cent) also said they prefer the products they buy there to any other supermarket.
Sixty five per cent of survey respondents believe their usual supermarket offers the best value for money, while 58 per cent find the quality of supermarket private label brands to be as good as the big brands and 46 per cent believe they could get their groceries cheaper at a different supermarket but prefer the convenience of the one they know best.
Seventy four per cent say it is important to them to buy locally produced food.
The Canstar Blue survey also asked respondents about their supermarket “pet peeves”. Topping the list was long queues at the checkouts (62 per cent), followed by desired items being sold out (52 per cent), self service machine errors (38 per cent), parents not controlling misbehaving children (38 per cent) and aisles being blocked by trolleys (36 per cent).
Megan Doyle, Canstar Blue, business unit leader, said Aldi has received consistently strong results.
“We know that supermarket shoppers want to feel they are getting a good deal when they pass through the checkouts.
“Aldi has maintained five star ratings in terms of the quality of products and special deals offered. In a highly competitive industry, that is a fantastic result.”
Aldi also received a four star rating for customer service and accessibility of staff, and three stars for range of products.
“For over a decade, Aldi Australia has focused on offering our shoppers high quality products at permanently low prices every day,” said an Aldi spokesperson.
“We take great pride in our proven ability to provide a smarter shopping experience, from the value, quality and freshness of our products through to the convenient and efficient store layout.
“At Aldi, we listen to customers and we are consistently looking at ways to improve and bring new innovation to the marketplace.”
