 Both of ANZAC's frigates are currently over in Canada getting an extensive midlife upgrade. So what are the upgrades our frigates are actually getting? 

Yes both, there was a delay with HMNZS Te Kaha, due to a mix up with cables, however this has been rectified and Te Kaha is on track to be back home  November/December 2020 and HMNZS Te Mana is still on track to be delivered back on the original schedule.

Update HMNZS te Kaha is now doing her sea trials.

First off let's look back and see what our frigates already had and could do.  Our ANZAC's are classed as a multi-role frigate meaning they can fit in anywhere as part of the fleet, from air support to ASW to fleet support. However, the frigates were built in the late 1990s and based on late 1980's designs. So they are getting on in age. HMNZS Te Kaha was laid down in 1994 and launched in 1995 commissioned in 1997. So from commission date to now (time of article), she is 22 years old. The tech on board is old and outdated. The wear and tear means the are getting harder to maintain.



Due to this, most navies have maintenance schedules and mid-life refits, etc and the RNZN is no different. The problem is since when are now down to only two frigates it makes it very difficult to have a decent refit period because you run the risk of the 2nd frigate needing some maintenance and therefore have no frigates on standby.
