The number of patients waiting more than the four-month benchmark to see a specialist has jumped 46 percent in the last year.
Te Whatu Ora's latest quarterly clinical performance data - released on Tuesday - shows there were 51,274 people in June who had been waiting longer than the benchmark, compared with 35,080 at the same time last year.
Preventable hospital admissions (known as "ambulatory sensitive" admissions) for babies and preschoolers shot up 35 percent, particularly in Auckland.
Pasifika children aged 0-4 were the worst affected, with their hospitalisation rate increasing 45 percent.
"There has been a particular increase in the rate of admissions for asthma, pneumonia, upper respiratory and ear, nose and throat infections, gastroenteritis/ dehydration and cellulitis over the 2022/23 year - the first full year with no Covid-19 lockdowns in place," the report said.
Te Whatu Ora interim chief clinical officer Dr Richard Sullivan said the data covering 12 clinical measures (from immunisation coverage to emergency department wait times) provided "a snapshot of the current challenges in our health system".
"Our workforce and the capacity of our primary care and hospital system are still feeling the ripple effects of Covid-19. The pandemic had a significant impact on our waitlists and our workforce, as it did globally.
"There has been increased emergency department presentations and patient complexity, a surge in the number of young people needing mental health support, and the volume of treatments and outpatient appointments for cancer services has increased an average of 1.7 percent a year."
While demand has increased, Te Whatu Ora was delivering more services, he said.
"In the year to June 2023, we delivered 316,286 planned care interventions compared to 297,265 in the year to June 2022. This equates to 19,021 more planned care treatments, a 6.4 percent increase on the previous year."
