We have Griselinia hedging surrounding our property. However, with the recent temperatures reaching -15 degrees, I am almost sure the poor thing is in the throws of its last weeks. As it stands at the moment, all higher branches seemed to have dried out. At the very base of the shrub, the main trunk of it does seem to have some form a sap going into it. There is growth of at least five years, but we have to make a decision, try our best to save it if it's possible or remove it and replant before it's too late. Can you please give me some advice?

It might be able to be saved, but it will be iffy and if successful, it will take some time for it to achieve its former growth. It is not really a decision I can make for you. It is more of cost of new plants vs time and effort for the old plants. Most people decide to plant new rather than go through the effort. You can give it some nitrogen rich fertilizer. That will help to boost the foilage growth.
