PENNY SIMMONDS (National—Invercargill): Thank you, Madam Chair. Perhaps while the Minister is getting that advice, I could put some further questions forward. As my colleague just talked about earlier, this import of low-sulphur fuel is going to be required, and I wonder if the Minister could tell us about any modelling that has been done in terms of the potential cost to domestic operators and also a time line for implementation. Given that there is going to be this additional cost for domestic operators, I'm sure they will be wanting to know a little bit more detail about time frames and when they need to be budgeting for this. Thank you.
