key training elements
Key Training Elements

Effective interviewing comes about through

officers being exposed to a regime that


  • understanding theory including psychology and how memory works
  • a range practical techniques
  • significant opportunities for practice
  • a wide range of interviewing experiences with ongoing monitoring and feedback from supervisors
  • workplace and formal assessment
level 3 specialist adult witness
Level 3: Specialist Adult Witness
  • Introduction of ability to use visual record as evidence in chief (Evidence Act 2006)
  • Improvements needed with adult sexual assault victims
  • Initiated with UK experts now our own experts
  • Fast-track select group through to Level 3
  • Developing our own expertise
co ordination and delivery of training
Co-ordination and delivery of training
  • Dedicated trainers at the Royal NZ Police College – recruits, Level 2-4
  • District roll-out for back-capture 6,500 frontline staff
  • Target influencers: Sergeants, Field Training Officers and Workplace Assessors
  • Level 2 and 3 candidates
  • Initiated with UK experts
  • Growing our own expertise
competency framework
Competency Framework
  • National Standards
  • Ongoing supervisor monitoring & feedback
  • Workplace learning and assessment:
    • Verification
    • Accreditation
    • Adjudication
    • National Register
  • Performance appraisal linked to pay increments
  • National Assessment Centre
  • Communications strategy ensuring the right people get the right information at the right time:
    • Road show - sell I.I. to District Management Teams
    • A successful pilot in one of the countries busiest stations
    • I.I. begins to sell itself, staff are lining up to undergo the training – satisfied customers
    • Availability of myself and team to assist frontline investigators
    • Intranet site with Good Practice Materials, preformatted statements for producing interviews as evidence in chief and much more
has a change in culture been achieved
Has a change in culture been achieved?
  • 6,300 of the 6,500 frontline staff have received the foundation training – a change in culture is occurring
  • Assessment and Accreditation intrinsic to the programmes success is slow
  • Investigators appreciate the I.I. more and the CIB are beginning to utilise the L3 ECI much more
  • As investigators begin to develop their skills they are seeking further (L2) training and looking to L3 Suspect Training
  • Investigators regularly talk about I.I. no longer is it about getting a cough (confession) or just taking a statement
  • Acceptance of research
how is i i progressing
How is I.I. Progressing?
  • We have an I.I. strategy with national standards and structure supported by training staff and facilities
  • We have the bulk of frontline staff with at the very least a foundation knowledge of I.I.
  • A growing pool of investigators who wish to improve their skills and experience as interviewers
  • We have the CIB appreciating the value of well conducted L3 witness interviews the demand increasing as well as the interviewers experience and expertise
  • L2 I.I. is now being trained and our skill base for advanced interviewers is developing
  • Initially resistance to the five day training programme – discretionary not mandated training
  • Ensuring consistent training across the country – L2 is only trained by our trainers L1 was district based
  • Lack of understanding of the assessment and accreditation requirement – as identified by our recently completed process evaluation – need for greater supervisor influence
  • Finance – VHS to DVD migration, interview room upgrades, software and hardware developments
  • Lack of understanding from CIB managers of the L3 I.I. techniques – similarly for Crown Solicitors and Judiciary
  • Managements demand on my time/role
  • Transcription
  • Our overall commitment to I.I. and how far we have come since November 2007
  • My small but fantastic team who have created I.I. in NZ and who through their work champion I.I. every day, I am particularly proud of them
  • A sound L3 training, assessment, accreditation and peer review process
  • Our developing interviewing skill sets with some exceptionally good L3 interviews which are now beginning to filter through the courts
  • Selling I.I. to police and now to Crown Solicitor’s and the District Court Judiciary
  • Involvement with research
our influence internally and externally
Our Influence Internally and Externally
  • Internally is detailed above
  • Externally we have been approached by 43 agencies wanting us to teach them I.I.
  • Regularly we are asked to present on I.I. – Innocence Project of NZ, Legal Groups/Business Groups and even Medical Practitioners
where to from here
Where To From Here
  • Complete the culture change to I.I.
  • An evaluation in about 18 months time replicating the initial review conducted by Mary Schollum so we have an accurate view on what we have achieved and what we have to do to be a World class police Service based on the core of policing, I.I.
  • Develop our L3 Suspect Training programme and implement it
  • Identify suitable I.I. Advisors and have them trained
  • Bring Child Evidential Interviewing under our team and develop a assessment and accreditation process supported by 6 monthly peer reviews
  • Advance our technology to support I.I. with down streaming, a national virtual transcription service and centralised assessment centre to ensure consistent accreditation standards
  • Voice recognition software
  • More Research
