"We expected 126,000 kits to get us through the weekend, but demand has simply outstripped supply at many collection sites," McKenna said.
She said delivery of an additional 24,000 RAT kits were due to arrive last week but were held up with arrival expected today .
An additional 126,000 RAT kits were also expected to arrive tomorrow .
McKenna said anyone with Covid-19 symptoms and needing a test should visit a drive-in testing centre to help reduce demand at collection sites.
"Drive-in testing centres still have RAT supplies, which we expect will get us through until stocks are replenished," she said.
"People can also keep an eye on the Healthpoint website to find out what collection sites are open and have RATs available for pre-order, but supplies will be limited.
"Providers and the DHB are working incredibly hard to meet demand but are reliant on the delivery of RAT supplies, so we thank people for their understanding as we work through these teething problems together."
Today in Hastings, Bay Plaza Pharmacy was awaiting RATs but Unichem Pharmacy, a collection point for RATs, was stocked.
A staff member at Bay Plaza Pharmacy told Hawke's Bay Today they had been inundated with calls from people wanting to get their hands on RAT kits, but there was little they could do because they were waiting on couriers.
People who need supervised RATs for NZ Travel and NZ Courts can get it, by appointment only, from Unichem Russell Street, as well.
Supervised rapid antigen testing (RATs) is for unvaccinated people with no Covid-19 symptoms, who require evidence of a negative Covid test result to travel within New Zealand, or for entry into a court of law.
For travel, the test must be done within the 72 hours prior to travel (preferably within 24 hours).
For court attendance, the test must be done within 24 hours.
The DHB wanted to remind anyone who tested positive to report their result.
You can do this through the My Covid Record web page or call 0800 222 478, option 3.
