"We get our produce locally in Onekawa and generally get good regular supplies of fresh vegetables.
"We have had funny weather though and the intense heat is causing crops like spinach to bolt and go to seed and dry out.
"Rain is the best thing, but then if there's too much then things like iceberg lettuces start to rot.
"The seasons seem to be getting more changeable and unpredictable so the prices can go up and down."
She said as retailers they tried to keep the price steady, which meant the business did not make as much money at times in an effort to keep costs down for customers.
The same was the case at Shires Fruit and Vege Market in Dannevirke, where owner Suresh Patel said everybody across the country was being affected by the humid, hot growing conditions.
"We source our produce from all around the country and have had to go as far as Waikato and Pukekohe, especially to get cauliflower."
He said that last week, the cost price of cauliflower was $8.15 and that many independent stores sold at cost or below cost in order to keep stock rotating and keep prices as low as possible.
"That's just what we have to do at the moment, but cauliflower is a good example where the price can crash again within 10 days."
He said there was still some big heads of good quality broccoli around, which Shires was selling for $4, but he said there would be a lot of stores and supermarkets putting a mark-up on that.
While the green vegetables may have spiked in price due to the shortage, on the plus-side there were some very good deals around for pumpkin and kumara, he added.
Ms Laird said frozen vegetables were always good value and a readily available alternative if the cost of fresh produce was too high for the budget.
