HCC deputy chief executive Lance Vervoort said originally the matter would be discussed at last week's full council meeting, but asked councillors if they could push it back to this month's community and services committee meeting on February 19.
"The mayor pointed out to me our consultation with iwi won't be happening until next week, and council does not have the Maangai Māori sitting on it, but the community and services committee does," Mr Vervoort said.
"We thought it would be prudent to carry this over to the C&S meeting, so we can get feedback from the Maangai Māori, and that you get the full information when making a decision."
The staff report said the proposed art work would be "temporary". Murals, in general, have a limited lifespan of five to seven years, depending on environmental conditions and the use of the space.
The Municipal Building is scheduled to be repainted during Year 4 of the 10 Year Plan in 2021/22. If the mural was not painted over during the scheduled repaint, the cost to repaint over the mural at a later date would be about $12,000.
