How to keep your avos looking their best - because no one likes brown guacamole.

Avocado lovers rejoice – prices for the creamy summer delicacy keep plummeting.

In May, single avocados were selling for as much as $12.50 each at a fruit market in Auckland. But warm weather has brought financial relief for consumers.

On Tuesday, Healthy Harvest Fruit and Veges in Prebbleton near Christchurch priced its avocados at 18 cents.

This follows another Christchurch shop, Vegeland on Marshland Rd, setting the trend at 29 cents a piece in early October. Last week, they were 89 cents at Pak'n Save.

Healthy Harvest had a no-limit special on Tuesday to move out a large number of firm, small and medium-size fruit due to ripen over the next few days.

He said "big, bulging bags" could be seen in the hands of many customers at the three checkouts.

iStock Avocados are a healthy source of monounsaturated fats and contains nearly 20 vitamins and nutrients.

His avocados come from Bay Farms NZ – a family business with more than 200 growers across the country. Most of the avocados shipped to Christchurch come from the Bay of Plenty.

Gibson said despite fluctuating prices, avocados were in demand throughout the year.

Often described as a guilt-free food, the fruit is a healthy source of monounsaturated fats and contains nearly 20 vitamins and nutrients.

Consumers can still expect further price one-off price drops.

Earlier in the week, Vegeland sold a couple of crates of very ripe avocados for 5 cents each. These disappeared almost immediately.
