Conservation Treatments

Conservation Treatment - Easel Paintings

We specialise in the conservation treatment of easel paintings and large artworks.  Materials can include oil, mixed media and acrylic on various supports from canvas , wooden panel and tapa . Thanks to years of expertise we can work with old or contemporary artworks.  The treatment of paintings can include detailed analysis of the pigments present in the artwork, microscopic investigation and examination under ultra violet light.

We can assess the paintings at our Studio or we can come to you (by negotiation).

If your painting has been torn or marked,  if there is water damage or mould present we can provide an assessment and then carry out the conservation treatment.

We follow the code of ethics laid out in the NZCCM Code of Ethics.

The Children of King Charles I - Gregory Baughen, Official Secretary, Government House

As I write this, the painting of The Children of King Charles I is back at Government House in Wellington, in its rightful place in the Norrie State Dining Room. It is positioned directly in the eye-line of the Governor-General’s place at the dining table, and will quickly become part of Her Excellency’s experience of the House and her vice-regal role.

I thank you for all that you did to bring this painting back to its proper condition. Government House, now and in the future, extends its gratitude to you.


At Studio Izzo we restore and conserve a wide range of objects. This includes marble, sculptures of many mediums, ceramics and wooden objects.

We have also worked with iwi and hapū to conserve and maintain marae and taonga. In our treatment we respect tikanga when dealing with Māori objects.

The conservation treatment is dictated by the type of material. Following consultation, our assessment will provide a plan to repair and conserve your object. The chosen treatment is decided after discussion with the client.

We may also conserve broken pottery and china through the ancient Japanese art of Kintsugi (金継ぎ) or “Golden Joinery”. This is an approach which will restore your broken but beloved objects while paying respect to the history of the object.

The aim of our conservation treatment, as per the rules of ethical conservation, is to make the process reversible.
