Assuming it's voicemail messages arising from calls from your UK mobiles

set a permanent call divert on a 3 PAYG SIM. Try it for yourself on your
own 3 SIM.
If forwarding works, you could sign up for a VOIP service and either set
an addtional call-forward from *that* service to a local NZ mobile (once
you know the number), or access any voicemail messages from calls
(originally destined for your mobile) via the VOIP service web interface.
If you are expecting a lot of calls you should opt for VOIP service with
an assigned UK geographic number, to minimise the cost of the diverted
mobile calls to VOIP:
e.g.
https://www.sipgate.co.uk/sipgate-starter
or VOIPfone with an add-on geo number:
https://www.voipfone.co.uk
If you do want the calls to be routed to a NZ mobile number you could
then forward the VOIP service to it - it will cost you about 12p minute.
BTW, I have a PlusNet SIM and unconditional call forwarding doesn't work
for me, even though the service and phone suggest it is correctly set
(!) Calls to the so-called forwarded phone instead receive NU tone.
EE, Tesco - no idea, sorry.
