The council would follow the Government's direction about any community events or joint time for mourning, he said.
Northland MP Matt King said the attacks were carried out by a "lone nut-job" who did not represent New Zealanders.
"I am encouraged by the coming together of everyone and support from everyone."
More than $6.7 million had been donated to victims on an official Givealittle page by edition time on Wednesday.
A group of around 40 people marched down Kaitaia's main street at midday on Tuesday as a sign of respect for the Christchurch victims.
The quickly organised event ended at Te Ahu centre with waiata, prayers and speeches. Many women wore scarves on their head in solidarity with Muslims.
There was also plenty of support for Muslims on social media, including a heartfelt post on the Northland Grapevine — Info Sharing Group.
"To any members of the Muslim community here in Northland: if you don't feel safe walking home, waiting for the bus, doing your groceries or anything else — we will walk with you, we will wait with you, we will support you," read the post, which was supported by 1300 people.
St Saviours Anglican Church in Kaitaia was one of many churches around the country which held a dedicated prayer service on Sunday.
Vicar Dino Houtas said the service was a call to 'lift up' the victims and the nation in prayer. The national anthem was read, and there were many tears, he said.
"We're absolutely grieved by what has happened to our Muslim brothers and sisters in their place of worship, and we stand with them in mourning."
Mr Houtas said there were some new faces at the service.
"What was most striking was the depth of grief and sense of unity and love within our diverse town and nation."
In Paihia, about 40 people gathered at Horotutu Park for karakia, speakers and shared a picnic meal. They invited tourists and passers-by to join them.
"It was really about getting to know our community, and getting strength and love from that," organiser Rae Smythe said.
Flowers, cards and painted messages have been popping up in tribute at various locations, including the corner of Kerikeri and Cobham roads in Kerikeri.
The messages include "New Zealand is their home: They are us" with a photo of some of the victims, "Love always wins", a quote from Martin Luther King, and a child's plea in felt pen: "I hope these fights stop".
Marian Andrews said she started the Kerikeri tribute garden with a sign and some flowers on Saturday, and had watched it grow: "I was pretty upset, it knocked me for six. I wanted to do something, we're far away but we can still show our support for people who need it."
