Mr Hill said the test results would have warranted an urgent grading or immediate hospital admission.
Mr Hill said Dr E could have both spoken directly to the cardiologist and stated in his letter that the results were "strongly positive" rather than saying "positive".
The commissioner noted Dr D's "criticism ... [of] Dr E's 'failure' to provide full information" but, although accepting the letter omitted a detailed summary of the test findings, he did not agree this was a failure, because the test results were sent too.
Mrs Searles said the failure of the referral to be processed in line with Auckland District Health Board's own policies was disturbing.
She intends to write to the Auckland DHB's chairman, Lester Levy, to ask what he is doing to change his organisation's culture.
Auckland DHB's acting chief medical officer, Ian Civil, said managing referrals was a shared responsibility between the referring clinician and the clinician to whom the patient was referred.
"We will be working on checking and improving each of the steps we all need to take in the referrals process. We all want the best outcomes for patients."
