Bell Produce Ltd, which is run by local iwi Te Rarawa, provides 1500 lunches to four schools in the Far North each day, including Kaitaia Primary and Kaitaia College.
Kaitaia Primary principal Brendon Morrissey called Wednesday's late lunch a "hiccup".
"There wasn't much to them [the lunches] as many would hope," Morrissey told the Herald.
However since the programme started at the school on the first day of term 2, Morrissey said, it has been "superb".
Bells Produce Ltd acknowledged on Facebook the feedback they received on cooked meals and apologised.
"We are sorry cooked kai to schools was delivered late to certain schools across the days."
Retail manager Dion Harrison said they underestimated many things that were necessary to ensure the cooked lunches were of the quality they needed to be.
"We have learned a lot regarding the hot lunches and we will ensure our standards of food quality and timely delivery are better managed."
To make sure the issue doesn't happen again, the company has decided to split hot lunch days over two days. On Wednesdays, Kaitaia College will receive their hot meal and the other three schools will receive their hot meals on Thursdays.
Morrisey welcomed the change, calling it a "smart decision".
"Some of the complaints were about portion sizes and the type of food. While we are working to the Ka Ora Ka Oka guidelines we promise to review the menus and see what we can add or change," the lunch provider said on its Facebook page.
"Every day we are constantly reviewing menus, portion quantities and how we can improve," Harrison said.
The Ka Ora, Ka Ako/Healthy School Lunches Programme includes primary, intermediate and high schools and is not decile-related.
Nearly 15,000 students across the region will have a free healthy school lunches this term, courtesy of the programme.
At first Morrissey was concerned about how students would react to trying new foods, but he told the Herald many of the student's plates were returned empty and many kids were coming back for seconds.
