Grant is recognised as a highly experienced Specialist Heavy Vehicle and Motor Fire Investigator and is requested first to undertake all investigations of this nature. He is known within the industry and brings a high calibre investigation process to the Corporate Risks team.

Since joining Corporate Risks in 2008, Grant has been involved in many origin and cause investigations allowing him to utilise his expertise in this field.  As part of these investigations, he has been called upon to give his expert opinion on fire scene evidence as well as court evidence in a trial, as a prosecution witness, but more specifically as an expert Fire Investigator. During cross examination, Grant was intensely examined in relation to his skill, methodology, knowledge of fire investigation and his conclusion. The Jury subsequently convicted the accused on the Arson count and on 7 April 2011, he was sentenced to 5 years imprisonment.

The Detective in charge of the case stated; “I found Mr WEAVERS to be an extremely competent and a very experienced Fire Investigator with sound knowledge of fire development. His ability to explain technical aspects of the examination in simple language certainly assisted the Court, and allowed the Jury to make an informed decision”.

​Grant’s 33 year career with the New Zealand Fire Service commenced in 1974 when he joined the Palmerston North Fire Brigade as a recruit fire-fighter, progressing through to the rank of Senior Station Officer operationally until 1997, when he transferred to Fire Safety.

Grant’s fire origin and cause work within the Fire Service has given him extensive experience in this field. While operational, he was the officer in charge at fire incidents and responsible in determining the origin and cause.  During the past ten years, his role as a Fire Safety Officer providing specialist assistance to operational officers, has been further enhanced with investigations of origin and cause being a large part of his work.

Grant’s role as a Fire Safety Officer carried administrative portfolios which included preparation of fire investigation reports for the district courts, giving evidence as an expert witness and co-coordinating the Fire Awareness Intervention Programme.

Grant’s 10 years as a Senior Station Officer in the Western Fire Region Fire Safety Office involved him giving building compliance advice to building owners, architects, fire alarm agents, district councils and the general public.  This gave him considerable experience in dealing with: - The Building Act, Building Code, Fire Service Act, the Fire Safety and Evacuation of Buildings Regulations and associated New Zealand Standards.
