The New Zealand Institute for Public Health and Forensic Science (PHF Science) was formerly named The Institute of Environmental Science and Research (ESR).
PHF Science staff, using our accredited laboratories, undertake a range of testing. Our test forms are available here, or visit our testing & analysis services page to find out more. Note as we transition to PHF Science from ESR, some forms may reflect our former name. We will still accept samples on ESR-branded forms.
