But analysis showed that some environment areas were down on previous years' spending.
They included funds for the Ministry for the Environment to buy or develop assets ($1.34m, down 25.8 per cent), for implementing support around RMA management policy and practices ($12.9m, down 12.1 per cent), developing a national carbon accounting system to meet obligations under the Kyoto Protocol ($2.25m, down 37.8 per cent) and investigation and management of contaminated sites ($4.24m, down 38.8 per cent).
The well-signalled Green Investment Fund (GIF) would get a $100m kickstart from the Government, and aimed to attract billions of dollars in private investment to attract new jobs and wealth from green business.
"It's the greenest Budget ever, a win for our people and planet, and represents transformational change," Green Party co-leader and Climate Change Minister James Shaw said.
Shaw said the GIF would "stimulate significant private-sector finance" into the low-emissions projects and businesses.
"In places like Australia, the UK and some US states, green investment funds have been hugely successful, attracting capital to fund low-carbon transitions and reduce climate pollution," he said.
"As Mōhio's recent climate-finance report states, global capital is already shifting into climate-aligned investments."
Set to be established by the end of the year, the fund would repay initial Crown operational funding once self-sustaining, Shaw said.
Elsewhere in the climate space, an extra $14m would be spent passing a Zero Carbon Act, amending New Zealand's emissions trading scheme, establishing an independent Climate Change Commission and continuing efforts to make good on targets set under the Paris Agreement.
In the conservation space, as announced on Saturday, $181.6m would be spent over four years, marking a funding boost for the Department of Conservation.
That included an extra $81.3m in operating funds for predator control, enabling DOC to battle possums, rats and stoats over more than 1.8 milllion hectares.
Conservation Minister Eugenie Sage said DOC's pest control improves forest health and the breeding success of threatened species like kaka, kea, rock wren, whio and bats.
"When 4000 of our native plants and animals are threatened or at risk of extinction, every single conservation dollar counts."
Also banked was $16.2m for DOC to strengthen its core capability and capacity, $5.5m to improve tourism management with new strategies in areas like transport and waste management, and $2.6m to fund better protection of the South Island's biodiversity-rich Mackenzie Basin.
"The total Vote Conservation baseline will have increased by an additional $60.2m annually by 2021-22, representing a 13 per cent increase on the 2017-18 conservation budget," Sage said.
She said there had been no Cabinet decision yet on a levy for international tourists, but an announcement around that was expected soon.
The $5.5m spend involved "being more strategic" around tourism, and "how they can be moved around better, rather than putting in ever-expanding carparks and the like".
On the MacKenzie Basin funding, she had been left an "omnishambles" after intensive development had been allowed in the region.
Efforts to protect the basin weren't working, she said, and although the spend would go some way, it wouldn't solve all of the issues.
Meanwhile, $3.1m has been allocated over four years for a new unit to oversee the Resource Management Act (RMA), which is itself set to be reformed over coming years.
"At present compliance, monitoring and enforcement actions are somewhat variable across councils," Environment Minister David Parker said. "The unit will improve the consistency, effectiveness and transparency of council enforcement of RMA rules and decisions."
Under the RMA, local authorities are delegated responsibility for the everyday management of land, freshwater and other resources, and for ensuring that growth and development occurs within the environmental bottom lines of the RMA.
These responsibilities include making local plans and rules, and processing and deciding resource consent applications.
Land use was mainly the responsibility of district and city councils, and freshwater use and quality that of regional councils.
"The establishment of the oversight unit will complement guidelines developed by councils to meet their responsibilities," Parker said. Legislative reforms requested by councils, such as extending the limitation period for prosecutions from six months to 12 months, would be considered as part of the RMA reforms.
Other big figures in the Vote Environment package were $1.7m over the next two years for an investigation into sites contaminated by per- and poly-fluorinated alkyl substances - mainly firefighting foam - and $8m of new operating funding over the same period for the Environmental Protection Authority.
Shaw and Agriculture Minister Damien O'Connor further announced $15m of new operating funding over the next four years for the Sustainable Farming Fund (SFF).
"The Sustainable Farming Fund encourages unique collaborations among farmers and growers, scientists and researchers, iwi, local government and others who are making a real difference for our rural communities and the wider primary industries," O'Connor said.
There had been an oversubscription to the fund in recent years, meaning good projects aren't getting a look-in because the previous Government did not provide enough investment for the fund, O'Connor said.
In the last SFF round, 86 eligible applications were received but only 28 of these could be accepted.
However, Greenpeace questioned why the Government was spending $800m each year subsidising greenhouse gas pollution from agriculture, and not folding the sector into the emissions trading scheme.
"That's $800m a year that could be spent on providing critical public services for New Zealanders, not to mention cleaning up our environment and accelerating the transition to a clean, low-carbon economy," its head, Russel Norman, said.
"Despite acknowledging the urgent need for action on environmental issues, the Government's spending does not match this urgent need.
"In fact the biggest spend on climate in this Budget is to subsidise agricultural emissions to the tune of $800m a year."
Norman suggested that some of the $800m recouped from bringing agriculture into the ETS could be used to support New Zealand farms to transition to regenerative farming.
Forest and Bird chief executive Kevin Hague saw this year's Budget as a good step forward.
"For the first time in a long time there's been a real increase in the natural heritage fund, which is the bread and butter for DOC's conservation work," he said.
"Still a ways to go before conservation funding is where it needs to be to reverse the decline of our native species, but this is a significant step in the right direction."
Fish & Game chief executive Martin Taylor was pleased to see the Budget would help improve Overseer as a farm management tool.
"The sustained assault on the environment in recent years has hurt the environment and hurt New Zealand," he said.
"Today's announcement of extra money to help fix that damage is a big step forward and very welcome.
"Farmers need tools like Overseer to be fit for the vital job they are required to do."
Environmental Defence Society (EDS) policy director Raewyn Peart was happy to see the 16
per cent increase on DOC's previous allocation.
"EDS has been arguing for some years that DOC has been chronically underfunded for the job it does," Peart said.
"We see the increased funding as a vote of confidence in the DOC leadership team.
"After some years of debilitating and distracting restructuring, the department is finally settled and able to manage an expanded budget with the clear expectation that additional outputs will be delivered efficiently and effectively.
"We expect to see expanded staff levels within the department with increased policy, science and RMA capability."
