Pak'nSave (stylised as PAK'nSAVE) is a New Zealand discount food supermarket warehouse chain owned by the Foodstuffs cooperative. It is one of the three main supermarket chains in New Zealand, alongside Woolworths and New World (the latter is also owned by Foodstuffs). There are a total of 60 Pak'nSave stores throughout the country.

Pak'nSave stores are large and have a no frills environment, often with unlined interiors and concrete floors.

Pak'nSave had 20 stores in 1993, which rose to 30 stores in 1998. Its supermarket market share rose from 8% in 1989 to 24% in 1996.

The first Pak'nSave opened on 12 June 1985 in Kaitaia, a town in the Far North District of the North Island. In the beginning, mutton and candles were the stores best sellers, which is attributed to the fact that many homes in the Far North still did not have power in 1985. Pak'nSave originally used a system where customers were given a black marker upon entering the store, which would use this to write the prices onto the goods that they were buying, which they would bring to the checkouts. This is because Pak'nSave at the time did not use barcodes, scanners, or running checkouts, so prices were written onto shelves. Due to the first store's popularity in the Far North, Pak'nSave operated monthly bus trips to the Kaitaia store.

A couple of months after the first store, a second Pak'nSave store was opened in Henderson. Two days after the store opened, two more checkouts had to be opened because of its popularity.

In the 1992 recession, Pak'nSave increased its focus on prices.

In 2005, there were 37 stores around New Zealand, including seven in Auckland.

Pak'nSave started rolling out self checkouts around 2009, where customers would scan, pack and pay for their groceries themselves. Customers would only interact with employees to check IDs for sales of alcohol or cigarettes.
