Some hardware stores will be open only for trade workers who are working through.
This means food, medicine, healthcare, energy, fuel, waste-removal, internet and financial support will continue to be available, the Ministry of Business, Innovation and Employment (MBIE) said.
Many publicly accessible places have already had restrictions placed on them, with security controlling the number of people gaining access and contact they have.
Drive share services Uber and Ola will continue over the four-week period in the region, assisting with transporting people to health centres and supermarkets.
New Zealand country ,manager at Ola Brian Dewil said: "even in these moments of great uncertainty, many thousands of people are continuing to work selflessly to keep everyone safe.
"As a key service to help the community, we'll continue to operate across New Zealand and it is okay to keep booking rides during the lockdown."
A Hawke's Bay construction company is also going to offer its services on call during the lockdown period for cases of emergencies.
Wiffbuilt Building Maintenance and Construction owner Steve Wiffen said that they will be offering emergency services during the lockdown period.
"With everyone stuck at home for most of the day over the month long period there are bound to be problems coming up so it's just a matter of making sure we can help out and solve any issues people have," he said.
"I have a crew of three guys including a builder, plumber and electrician so we will cover most of the problems people will face."
He said that they will only help in urgent situations and are also following health and safety procedures in how they deal with jobs and people.
"We have strict cleaning procedures we will proceed with and follow social distancing rules but we will only attend a job in an urgent case anyway."
