While ultrasound technology is used extensively in maternity services, until now it had not been available to doctors and midwives who make visits to outlying areas.
Mr Moore said the availability of the portable scanner now allowed doctors to carry out quick checks of the baby's wellbeing without requiring the woman to attend the hospital's radiology department.
"This frees up the doctor and makes time-consuming travel for the family unnecessary."
Maternity staff said ultrasound scanning was becoming increasingly important for full assessment of a known or suspected pregnancy problem, prior to hospital admission.
Hawke's Bay District Health Board clinical midwife manager Roisin Van Onselen said Maternity and Gynaecology Services were grateful for the donation of the portable ultrasound scanner.
"Ultrasound services in rural hospitals such as Wairoa and the Chatham Islands are limited, and the Voluson-e ultrasound machine can be packed up into a small suitcase and taken along for obstetric and gynaecology specialist clinics in these areas," she said.
"The scanner is used daily in the antenatal clinic, allowing doctors to do quick checks of a baby's wellbeing without requiring the woman to attend the radiology department for a full ultrasound scan, and this frees up this valuable resource for other patients in the hospital requiring ultrasound scans."
Mr Moore said the main objects of the trust were to help with the education and training of therapists and nursing staff working with children, as well as assist through the provision of equipment and the development of procedures and protocols.
It had so far come forward with more than $100,000 in funding. The latest donation was the result of income from investments, as well as assistance from the Joan Fernie Charitable Trust and the Infinity Foundation.
