Absalon is not a frigate replacement, it is an alternative to a Canterbury type multi role vessel, a small LPH / LPD / LST, or OPV, IMO any navy looking to replace frigates with an Absalon type vessel is looking to down grade capability while attempting to disguise it as increasing flexibility.
If the NZ government were serious about increasing capability they would be looking towards replacing the ANZACs at end of life with three new globally competitive multi role frigates, Canterbury with a LPD or LHD (preferably two but you need to start somewhere), the IPVs with OPVs, then and only then perhaps consider replacing the original pair of OPVs with Absalon type vessels. Sound unrealistic enough?
This is pretty much the level of capability I see the RNZN needing before they could seriously consider looking at Absalons. You need to have the high end covered off by capable warships and enough of them to support having one in refit or repair at any time. You need a capable ship with a docking well and helicopter facilities to support army requirements and HADR throughout the region, to give NZ the ability to operating unilaterally if required. You need a robust EEZ patrol and enforcement capability with vessels that are capable enough to work outside the EEZ in support of the frigates as required or even in lower level coalition operations. Once all of that is done then, if there are resources to spare, you could invest in a couple of Absalons to support and complement the other capabilities.
