"We know there could be more that aren't being reported," she said.
"We want everybody to know police will continue to prioritise family harm incidents and we will come when you call. Everybody deserves to be safe, and feel safe."
Anyone with concerns or information about family harm was urged to contact police as soon as they could.
If people were in immediate danger and unable to contact police on 111, they were advised to leave their house and get out of harm's way.
While the lockdown restrictions brought new pressures to family and home environments, people's own safety came first.
"Get to a safe distance and then ask a neighbour, or a passerby (at a two-metre distance) to call 111 for you," Venables said.
"We realise this is a hard time for some families and we want them to know police are there for them.
"We know that for some people, home right now may be an uncomfortable or scary place."
Temporary accommodation for people under police safety orders was available to those who needed it.
Police, Joint Venture Business Unit and the Ministry of Social Development also had a number for men to call if they thought they were going to harm a loved on - 0800 HEY BRO.
The integrated safety response Whāngaia Ngā Pā Harakeke from the police and Family Violence Inter-Agency Responses were constantly assessing risk and linking victims, perpetrators, families, and whānau to support services.
"Our partners are a crucial part of supporting our communities and ensuring people get the help they need," Venables said.
"As part of the response in the Covid-19 environment, police is part of a family harm and sexual violence pandemic working group, which is ensuring the right groups are connected and working together on monitoring and response."
