Background The Q uality A udit ( BQA ) of B reast S urgeons of A ustralia and N ew Z ealand includes a broad range of data and is the largest New Zealand (NZ) breast cancer ( BC ) database outside the NZ C ancer R egistry. We used BQA data to compare BC survival by ethnicity, deprivation, remoteness, clinical characteristic and case load. Methods BQA and death data were linked using the N ational H ealth I ndex. Disease‐specific survival for invasive cases was benchmarked against A ustralian BQA data and NZ population‐based survivals. Validity was explored by comparison with expected survival by risk factor. Results Compared with 93% for A ustralian audit cases, 5‐year survival was 90% for NZ audit cases overall, 87% for M aori, 84% for P acific and 91% for other. Conclusions BC survival in NZ appears lower than in A ustralia, with inequities by ethnicity. Differences may be due to access, timeliness and quality of health services, patient risk profiles, BQA coverage and death‐record methodology.
