The Anzac replacement has a "pencilled in" timeframe circa 2027/28 Te Kaha and 2029/2030 Te Mana. Basically 30 years each of planned service. The P3K2 was mooted for replacement circa 2025/26 - though I have a feeling that the P-3K2's may be around a little longer due to its delay in entering service. Pushed out until the ANZAC are paid off so as to give "full value". That is a personal opinion only. Thus there will likely be a fiscal acquisition hump at the end of that decade. That said, long term acquisition planning and project management should sort this.
Nevertheless, it will be important that whatever rotary asset that goes with the future ANZAC and the possibly the OCV (SEA 1180) is fully worked through (As the OCV may well be part of the OPV and IPV replacement package as it will be with the RAN) - and there is substantial thinking that needs to be done around that - for example the synergies and divergence of required platfrom capabilities per the ANZAC II's - and our other vessels that are not focused on ASuW/ASW missions but other tasking profiles).
The SEA 5000 project does not really hit its straps and until later this decade 2018 iirc and the Romeo is going to be integral in that platforms functuality and it would make total sense that when we are moving over into our own ANZAC replacement we also operating Romeo's. In the mean time it seems likely that the Sprites will be with us for some time to come - in possibly 15+ years of service would be realistic and fit right into the ANZAC replacement timeframe. This gives us a decade long window to manage the introduction of likely Romeo's on to our future ANZAC decks and in my view (personal opinion again based on meeting JATF / current policy goals and that the DWP/10 was too intellectually lazy to put its balls to the wall and discern anything beyond the rhetorical) the Seirra for the OCV's and Canterbury replacement. (As well as the other assets such as the by then in service LWSV and future Tanker.) It also gives us some wriggle room and likely crossover just like the NH-90 introduction is crossing over with the Iroquios.
