Jeremy Trevathan

Principal Acoustic Engineer

  • Bachelor of Mechanical Engineering with Honours – University of Canterbury (2001)
  • Doctor of Philosophy in Mechanical Engineering – University of Canterbury (2005)
  • Member of the Acoustical Society of New Zealand (MASNZ)

Jeremy enjoys the challenge of working with a building design team to ensure the acoustic design contributes to a successful overall project outcome. In recent years Jeremy has been heavily involved with the Christchurch rebuild effort with important continuation projects, including the High Court and Temporary Court building complexes and Temporary Police Station; restoration projects including The Arts Centre; and new build projects including the Regional Centre of Science and Innovation Centre at the University of Canterbury.

Jeremy also has considerable experience in environmental acoustics including the preparation and presentation of evidence at Council Hearings, Environment Court and before Boards of Inquiry. These projects provide the opportunity to work closely with other engineers, along with legal and planning professionals. Jeremy has had considerable success in ensuring environmental noise emissions will be appropriately managed with recent involvement including Brookby Quarry Direct Referral to the Environment Court in Auckland, and the Northern Arterial Notice of Requirement in Christchurch.

Jeremy was a member of the latest Ministry of Business, Innovation and Employment (MBIE) group working to revise Clause G.06 Airborne and Impact Sound of the New Zealand Building Code, and a member of the ASNZ working group advising the Ministry for the Environment (MfE) regarding the National Planning Standards (2019). Jeremy is also the AES Member Representative for the Association of Australasian Acoustical Consultants (AAAC), a judge for the Association of Consulting Engineers of New Zealand (ACE NZ) Innovate Awards and a member of the MBIE College of Assessors.

Tracy Hilliker

Associate Principal Acoustic Engineer

  • Bachelor of Mechanical Engineering with Honours – University of Canterbury (2001)
  • Member of the Acoustical Society of New Zealand (MASNZ)
  • ASNZ representative for the joint New Zealand Australia Standards Committee EV-010 Acoustics Community Noise

Tracy has a keen interest in education projects and, due in part to the appointment of AES to the Ministry of Education / University of Canterbury Professional Services Panel, has had many opportunities to contribute to outstanding acoustic environments for education in both the public and private sectors.

The outcome achieved by Tracy and the team in the ‘Collaboration Space’ within the Science and Technology Building at Rangi Ruru Girls’ School is a perfect illustration of the value good acoustic design can add, with the April 2014 Rangi News bulletin describing the revelation of the performance-quality acoustics of the space during the opening ceremony – “As guests took their seats the Kapa Haka group performed from the stairwell. The crowd revelled in the unexpected acoustics of the building and for some, thought turned to future opportunities for the building beyond the teaching and research of science”.

William Reeve

Senior Associate Acoustic Engineer

  • Bachelor of Mechanical Engineering with Honours – University of Auckland (2011)
  • Member of the Acoustical Society of New Zealand (MASNZ)

William finds the wide range of projects encountered in environmental acoustics particularly interesting and his recent work includes assessments of noise from hospitality and function venues, various industrial sites, aircraft and many other sources.

He enjoys the opportunity these projects provide to learn about the internal workings of a wide range of activities, and the challenge of translating this understanding into a realistic and reasonable appraisal of the noise which may be produced.  This work requires a highly detailed and methodical approach – and the ability to pull together a large amount of data into easily understood and accessible outputs has been a key aspect in several of William’s projects.

Lately, William has also had the opportunity to watch building developments for which he has provided design advice taking shape around Christchurch including high profile mixed use development ‘The Terrace’, and the Forté Health surgical hospital.
