Incident Reporting Procedure I'm new to H&S in NZ too. Nice to meet you.
At my current workplace we have been going through a change of reporting procedures. It use to be paper forms but has changed into a online only forms which remain anonymous unless discussion form management is required. We have also simplified the form to be as quick and easy as possible. However it is still difficult to get staff to engage with it. There have been many times where I have filled out a form on someone's behalf because they are unsure or feel under time pressure.
My workplace has a few sites across the country and other sites have got observation and identification/done it cards. However trying to bring this onto other sites has been difficult. Tool box meetings are in some places and not others and seem to work really well encouraging group discussions and actions to be taken.
It is hard to get a change in culture here, however if the OFI forms are not producing accurate or sufficient data to create an incident management report then I guess you could suggest that your leaving your workplace vulnerable to hidden incidents, hazards and non-compliance.
Most of the time I don't think its the system, but the engagement between the system and staff. I think @Tony Walton, is right. Group discussions are better when talking about near misses and engaging staff in the system, but managing the data and keeping track of changes is another can or worms. Something which the forms/OFI need to fit neatly into.
