Vogel's is selling loaves of its coveted bread for just 28 cents - the price the Kiwi favourite sold for in 1967 when the company first launched.

The promo price is celebrating 50 years - but you have to buy a 2017-priced loaf to get the second at the discounted rate.

Retailers were free to price their loaves, however Vogel's recommended retail price (RRP) was $4.99.

The 28 cent price was calculated using the RBNZ inflation calculator based on Vogel's RRP.

Vogel's marketing manager Andrew Fenwick said a lot had changed in New Zealand in 50 years, but one thing which had stayed the same was a love of Vogel's bread.

"Not only did Vogel's launch in 1967 but New Zealand changed to the decimal currency that year too," he said.

"So, for those still thinking in pounds and pence, 28 cents is about 14d"

Vogel's special 1967 pricing is available for one week only from Monday December 4 at supermarkets nationwide.

The special price excludes the gluten-free range.
