HMRC letter indicating which NI record years were voluntary

A 2020 change to the law in New Zealand means that a UK state pension is tax exempt for people there based on the amount of years voluntary NICs have been paid. Do HMRC issue letters to confirm how many years on a person's NI record were voluntary in nature?
