Mrs Golightly said Ms Arnott believes that the then DOL should have put the safety of people as paramount as part of its investigation and closed the park until the investigation had been completed.
An MBIE spokesman said its actions regarding a separate incident involving Mr Price were appropriate.
"Once MBIE became aware of the incident it commenced an investigation. The Ministry needs solid grounds for closing an operation and the nature of the workplace activity did not provide for sufficient grounds to immediately conclude that closure of the park was required or defendable," the spokesman said.
"As required, MBIE was following due process and gathering information and evidence to reach a defendable decision as to enforcement action. Unfortunately, while this was taking place Mr MnCube was tragically killed."
He said Mr MnCube's death was a tragedy and MBIE has successfully prosecuted those whose responsibility it was to provide Mr MnCube with a safe working environment.
In December 2011, Zion Wildlife Gardens Limited was ordered to pay reparations of $60,000 to Dalu's partner after pleading guilty to one charge under Section 6 of the Health and Safety in Employment Act 1992.
In relation to the Coroner's call for legislative reform, the MBIE spokesman said the Ministry has received the report and is considering the points made.
"We will have no comment to make until that process is completed," he said.
*Zion Wildlife Gardens was placed in liquidation in 2011 and sold to new owners in February 2012 who operate from the premises as Kingdom of Zion. The new owners were not involved in the running of the park at the time of the accident.
The Kingdom of Zion did not want to comment, at this stage, on the coroner's recommendations for legislative change.
