Hi Brendon - I would be interested in who is asking you for LTIFR information. As indicated above its something we are trying to strongly discourage, however boards and procurement in NZ hasn't generally made the transition away yet.
There are plenty of good papers that show why it isn't a good safety measure including:
Acsi. (2019). The Future of Health and Safety Reporting A Framework for Companies. (Page 16)

Having said all this - I understand that sometimes you are put in a position where you just have to supply what you have been asked for. The best source of these kinds of stats used to be the ASX100 Citi reports. Happy to send through the most recent one to you - which I think was 2018 if that is useful. Just send me your email through
