My husband , now deceased, and I were sealed in the New Zealand Temple on May 26th 1967
but the ordinance is saying cannot request and showing as not done
Since you are living and privacy is very important related to ordinances completed for living people, your sealing to your husband will not show correctly while you are living. Ordinances for the living are kept in your Church Membership Records maintained by your unit clerk. You can check this information to be certain it is correct by checking with your unit clerk or a member of your bishopric.
If you have other questions, please let us know.
Just thought I would add, that you can look up your Sealing in the Membership tools on the churchofjesuschrist.org website or the Member Tools app.
Look up your own name in the Directory part of the church website or the Member Tools app. There is a Membership Information tab which shows your ordinances.

All the best.
